indestructable!
June 16, 2017
"You purchased this item on September 20, 2013."Today is June 16, 2017 and I am typing the review on this same keyboard almost 4 years later, our living room TV is almost 100% watched through the computer and this is its keyboard, we have three kids, and a Great Dane, this keyboard has been dropped countless times on hard terrazzo floors, sat on, stepped on, had stuff spilled on it, the case is cracked in several places the keys are sticky with god knows what but it just keeps on working, unlike other keyboards the letters are still legible, battery life is excellent, and the lock button is a great feature, my 8mo old can tap away (he loves it) without disturbing our show.it is a bit cramped for serious work but for surfing to the next show, email, general web use it is perfect balance small enough to live on the back of the couch, and just big enough to house a usable keyboard.i just ordered k400 plus, hopefully it will be equally indestructible. this k400 will go in the toddlers toy-box so he can tap away just like daddy.
A good product

Logitech Wireless Touch Keyboard K400 with Built-In Multi-Touch Touch pad, Black Is one of THE BEST keyboard i ever had!Pro: - never had problems with connecting on computers - easy to install - it works at big distance from bluetooth receiver - you don`t need mouse because you have the pad (not so many keyboards have this) - extra buttons helps a lot! Sleep mode, Volume Plus, Minus, Mute - I`ve changed batteries after 2 yearsCon - the important buttons should come with little bumps to be able to identify them with the tip of your fingersFor sure i recommend them and i would buy them again!
A Great LinuxCNC Keyboard And Touch Pad To Control CNC Machinery In The Shop
May 13, 2016
I've purchased probably half a dozen of these K400 wireless keyboards to use as portable keyboards on the LinuxCNC machines I build. They also serve as wireless pendants that allow me to jog the machines. This keyboard isn't optimal as a machine controller, but it's good enough for the girls I go with. For me, it's the overall optimized solution. I write G code using the K400, although the key spacing is slightly more crowded than a full sized keyboard, and I use the K400 to jog the machine, zero axes, touch off, etc. I've run several of these keyboards in my shop at the same time without a hint of interference between them. I previously had to use a wired keyboard when initially setting up the computers that controlled these CNC machines, because the BIOS didn't recognize the wireless keyboard while in the BIOS setup, although Linux never had trouble and always immediately responds to the K400 keyboard and touch pad as soon as it boots, but later versions of BIOS are able to use the K400 while configuring the BIOS. I'm amazed at how frugal the K400 is with the AA batteries. For my use, the batteries last more than a year, although I generally remember to turn off the K400 power when I shut down the computer. These are tough little keyboards that hold up well to mild shop abuse. I don't expose the K400 to a lot of metal chips or flood coolant, but they hold up well to a moderate amount of shop grime, drops to the floor, etc. There is a very good COSMO silicone keyboard cover available for the K400, but honestly, the K400 is inexpensive enough that it's probably better to simply replace it if it's damaged.
Good for small hands.
April 16, 2015
I got this to go with a little Alienware Alpha we bought for our 6 year old, so she would be able to play WoW without monopolizing her mother's computer (yes, I am either the worst parent ever, or the coolest, but she reads at around a 4th grade level thanks to the game). I've used a black version of the k400 for a few years now (in fact, I am using it to post this). It's a little cramped for my hands, but works perfectly for hers, and it's easy for her to move around her room as needed as well. Obviously using mouselook isn't quite as intuitive on the touchpad, but having only one input device to keep track of seems to work better.I wish they had kept the volume controls on the top row like the black one has, but other than that it works great for her. I also got the pink/white Cosmo overlay, which is also working well. I put rechargeable NiMH batteries in it, as long as she doesn't set something on top of it they last for weeks (if she does then they drain in a few hours, but it's comparatively painless to swap them out).
The Perfect Keyboard
January 15, 2015
I bought this keyboard solely to use with my Amazon Fire TV as I use it to make navigating Kodi and web browsing a ton easier (requires a rooted Fire TV for the web browser) you'll also need a keyboard to install a custom recovery to the Fire TV and since I didn't have one I bought a junky, wired one at Walmart and after seeing this wireless keyboard with a touchpad for only another $10 I took the wired back and ordered this. Since it's Logitech you know you're getting a solid device that works well for a great price. I've been using a Logitech wireless mouse with my laptop but could have used this keyboard when I had my laptop connected to my TV which I no longer need since I have a Fire TV. I assume it can also be used with other internet streaming boxes as long as they have a USB port and recognize USB devices. This keyboard is truly plug and play as it worked immediately with my laptop after plugging in the USB receiver and was the same case with the Fire TV. The only drawback with that is I couldn't even use the Logitech "Mouse and Keyboard Settings" with this keyboard as I thought I could use it to map keys and adjust the touchpad sensitivity (which you'll notice is up pretty high and can be all over the place) but no matter what I tried I couldn't get it to show up yet my Logitech mouse would. Maybe this keyboard isn't able to have it's settings modified. The shortcut keys and Windows function keys are a nice addition and surprisingly most work with the Fire TV (such as the Home button, the Sleep button, and function key actions.) The keyboard is sturdy yet light weight, has a nice sleek design, the batteries haven't needed changed yet, and the key presses feel good. The only slight con is the keys are a bit smaller than what I'm used to so I do make more errors although I don't type correctly to being with so for other people this might not be as much of an issue. There is a reason so many people use this keyboard, it does everything you need and works with just about everything. So if you need either a wireless keyboard or mouse you might as well just buy this keyboard and have 2 for 1, and paired with a dedicated Logitech wireless mouse you basically have the perfect setup for whatever you need to do.
Almost good enough to be the primary keyboard for your main PC. For a "living room keyboard" it's a home run.
May 7, 2014
This keyboard is a home run. Make sure you get the updated one that has dedicated volume and FN buttons. I use it for my mostly-media-consumption Chromebox, but it's better than a lot of full-size keyboards I've used.Range: 5 stars. Miles better than a bluetooth keyboard. My computer can be in a mostly-metal cabinet in a different room... still works. In comparison, my two bluetooth keyboards (Microsoft and Sony) drop keystrokes if they lose line of sight to the transceiver (even a thin wooden desk blocks the signal).Accuracy: 5 stars. Rarely if ever has dropped or duplicate keystrokes. Again, much better than my $80 Microsoft bluetooth keyboard.Form factor: 3 stars. Good balance of compact size and touch-typing comfort. I can pick it up with one hand at the top and bottom edge. The keys are slightly cramped but still better than a lot of full laptop keyboards I've had. The downside for me is that they relegated some standard keys to require pressing the FN key (all the keys F1-F12, for example), and other keys are hard to find (volume, for example). It looks like the more recent version has improved this, making the F1-F12 keys primary and giving volume its own row.Compatibility: 4 stars. All the standard keys work great on my Windows, Ubuntu, Linux Mint, Rapsbian, and Chrome OS devices. Some of the macros don't work (Lock and Home being the most notable). I consider that very well done.Value: 5 stars. At $25, this thing is a steal. As I mentioned, it's better than my $80 full size Microsoft bluetooth keyboard and I'd even prefer it for use as my primary keyboard at work if I had to choose.[EDIT 5/11/2014] I did a little research, and it appears I received the newer K400r instead of the K400 that I ordered. It turns out that the older K400 is the one with the primary FN keys and dedicated volume buttons. The K400r is an updated version designed for Windows 8. In this case (and in the case of Windows 8 itself), newer is not better. If you're considering this keyboard, careful which one you order and double check it after delivery. I got the wrong one. Not a big deal since it's a great product either way, but annoying.

Tonka Tested....Daddy approved!!
September 22, 2017
I have kids that dont like to keep thier hands off of things that are not meant for them to play with. (I.E. dads wireless keyboard) I went with a cheaper model so when they inevitably stomp on it, drop it, or spill something on it I wont be too heartbroken. Setup was easy... Plug in the usb dongle, remove the little tags from the surprise included batteries, turn them on and your set!! (On windows 10 at least). Very next day your son deciceds to drive his 1970s model Tonka dumptruck over the keyboard a few times, THEN proceeds to DROP said Tonka on top when he realizes hes been caught. Bet your envisioning keys everywhere, cracked plastic and death to my fancy new wireless keyboard huh? Nope!! 1 little scratch of the paint on the Win key! Not a stuck or broken key everything works flawlessly. Now dont go buying this thinking its indestructable, Can pretty much assure you it has a weakness, they all do, my kids just havent found it yet! Surprising little tidbit I read on the box and not in the description; the keyboard batteries last up to 36 months and the mouse goes for 18. If I get 6 months outta the (not advertised) included batteries Ill be a happy camper. My old set was lucky to get a month!! Anyhow everything with this set has surpassed my expectations by leaps and bounds. Its light, comfortable, and works fantastically from my couch (12 or so feet from the pc). Im not a power user or super gamer so did not need all the programable buttons and whatnot some of the more costly models include. But I am a cordcutter and my PC is mostly used for tv and movies. The volume keys are awesome for that. And i do like the other function keys. So for the price and features this is a deal and a half to me. Should this one get destroyed by my children I will definately reorder the same.
Great Device Combination, Cheap Price.
August 23, 2017
Great device combination, cheap price. I bought this pair because the keyboard in my laptop didn't operate reliably, and I needed that function to work for me without problems. This pair appealed to me for two reasons: first, it was wireless, so as long as I had a spare USB port for its dongle, which I did, I was in business. Second, it was so inexpensive that I assessed that I could buy it on speculation, and not feel badly about tossing it if it didn't do the job for me. As it happened, it has worked so well that I purchased another set, so that I could leave one at home and one on my campus, and avoid packing it when I went from home to campus. Oh, and, the feel of the keys is quite satisfying, in contrast to the laptop's own, and the mouse beats its touchpad utterly. What's not to like?
Amazing for the price
June 19, 2017
For the price, this is an amazing deal. I am by no means a keyboard fanatic, I do not care about the sound or feedback, but as far as I can tell this is a very solid keyboard and mouse. It's not very nice, it being entirely made out of plastic, but what can you expect from a $20 Bluetooth Mouse and Keyboard? The set up process was amazing, I put in the bluetooth dongle, flipped a switch on the mouse and keyboard and I instantly started using it, no set up required.At worst, the keyboard has hanged every now and then. Nothing appears on screen and then woosh, all of my sentances instantly type themselves out. That's only happened a few times out of the many hours I've used the set. Also, you won't have to change the batteries for a whole year pretty much, which is a relief.
while it is nice not having the red light underneath at least when ...
July 1, 2016
while its not the loudest keyboard i have ever had it you can hear when the keys fly back to the ready position. The wireless function i was able to get to work to about 35 feet away in a conference room with out a problem. for the price point I don't think this combo can be beet. I do wish there were a way to tell the mouse is on besides moving it around with the computer on. while it is nice not having the red light underneath at least when it was visible light you knew your mouse was working and on:) I will try to respond back when the battery dies in the mouse and keyboard respectively to give a good understanding of product life. This review was typed out on the keyboard!
Worked Perfectly and Wireless!
March 16, 2016
It seems as though once one person gets a wireless keyboard and mouse then everyone wants one! I have even had people steal each others at work so I went ahead and purchased a bunch knowing they go quickly. This is a basic wireless combo with a keyboard and mouse. It's not the fancy version but gets the job done. You basically take the usb piece and plug it into your computer and BAM!! it works with no wires. In my experience Logitech has been a good brand for these types of items. I haven't had many issues with them overall. Sometimes you will get it where it loses connection or someone else picks up your wireless and you'll see a phantom pointer moving on your screen. I haven't had these issues with these new logitech mouse and keyboard. I am very satisfied and so are my coworkers who use them! I have also purchased the upgraded version and it works well too! I would definitely recommend this product and brand.
Plug in the USB gizmo and pull the tab on the batteries in the mouse and keyboard to get power, and Shazam! It works.
August 1, 2015
I got this great package yesterday, and it replaced my old wired keyboard and mouse on my old HP computer. It works great. I had problems with the built in mouse pad on the Chromebook 15, and my RN wife was afraid that I might end up with carpal tunnel syndrome and to suggested I try this cordless set with my Acer Chromebook. So, I tried it on my new Acer Chromebook 15, and it worked very well.It works great, and may be faster with the mouse on the Chrome book versus the HP.I had been considering buying the Acer Chrome Desk Top. If I can use a system to transfer the Image to my HP VGA 22 monitor, I will use my Chromebook 15 for what I now use my HP for on my office desk.The only mild complaint, is I can't find a sleep key for my HP monitor. So, I just push the off button.

On Board With this Keyboard
April 10, 2017
This wireless keyboard is quiet, has good finger-feel, and hasn't had any typing issues. The keyboard layout is a little different than normal with the compact setup, and takes some getting used to, as does the compact size of the keys. Someone with larger fingers might find this keyboard a typo nightmare, but I've adjusted to it all right.The trackpad and buttons work well, and the support of gestures is great, but I still use a separate mouse because I can't get the same fine control with a trackpad.I did experience setup issues where the installation software had trouble finding the device, and it appeared to be a conflict with Windows 7. I switched to the old Logitech SetPoint software, and everything worked fine.
Almost perfect, but could have been better.
August 22, 2013
I ordered two of these keyboards because the prices were less expensive than Samsung's own SmartTV keyboard in addition they work with PCs and Macs. I plug in the unifying USB receiver into an available USB slot on the back of the television and the television instantly recognized the keyboard and it worked pretty well. Both the keys and the trackpad moved the mouse pointer on the television easily. Some of the Fn function keys such as F7 and F8 replicate channel changing buttons, F8 brings up the television's menu. It just takes a little trial and error to figure out what function they perform on the television.I also have a Dell Laptop with a Logitech mouse that uses an identical unifying USB receiver. I didn't not have any problems mating the keyboard with the receiver on the laptop and the keyboard and pad worked flawlessly.The one thing about this keyboard that bothered me was the right handed shift key. My bad really, I should have noticed the layout before ordering. I'm a full keyboardist and the right shift key is practically useless because it is so tiny. This keyboard would have been perfect had they decided to move the arrow keys underneath the track-pad. There is plenty of room for the arrow keys there and it would have given more room to put a full-size right-hand keyboard. If you type with all ten fingers, the right-hand shift key may bother you. On the positive note, since the Samsung television works with the unifying receiver, it would seem that any other Logitech wireless keyboard with a unifying receiver would work with these televisions. But finding a small one with a track-pad might be difficult. For this oversight, I took away one star.By the way, the Samsung television I paired this keyboard with is a 2013 model Samsung UN55F6400 55-Inch 1080p 120Hz 3D Slim Smart LED HDTV. A friend of mine has a 2011 D8000 series and I will bring the second keyboard over to his house and see if the keyboard works with these earlier televisions. I'll update my review when I find out.Update 8/25/2013 ===============================I had the opportunity to try out the second keyboard on Samsung UN55D8000 55-Inch 1080p 240Hz 3D LED HDTV (Silver), Samsung UN46D6400 46-Inch 1080p 120Hz 3D LED HDTV (Black) and a Samsung UN32EH5300 32-Inch 1080p 60 Hz LED HDTV (Black). Of these three television sets, only the UN32EH5300 recognized the keyboard. This leads me to believe that this keyboard will only work with 2012 models and newer and not the 2011 Samsung TV. So if your Samsung television has a letter "E" or later letter in the alphabet in the 5th character position of the model number, this keyboard will likely work with your television. If it has a letter "D" or preceding letter in the alphabet, you are probably out of luck :(I hope this helps anyone with 2011 models and earlier. If you have a 2012, you are probably good.
Worthwhile for use with a Samsung Smart TV
December 23, 2012
Bought this to work with the Smart-TV features of Samsung ES7500. As many have pointed out, it works fairly well given the limitations of the TV itself. Installation was very straightforward, just plug in the dongle. Then go to a keyboard setup menu, where the keyboard was found immediately, and then to the mouse setup menu, same thing. Everything worked fine. Except I thought that the keyboard was not working with the browser. I thought, oh no, thats really dumb. But I noticed I was in the link browsing mode of the browser (the arrow keys were working and moving me from link to link but I could not enter text -- I later noticed that there is an implicit mode indication at the bottom of the screen). I had to use the Samsung remote to change to pointer browsing mode, and everything was OK.One thing that surprised me pleasantly was that even while watching a tv program, if I gestured on the touchpad, the pointer appeared, I clicked and a Samsung menu popped up and I could choose to enter smart tv mode without using the samsung remote. Score one for Samsung.Also, a very nice feature is the inclusion of a mouse botton on the upper left corner of the keyboard. I use that all the time to select stuff. It sounds odd, but it really works well to hold the keyboard in left hand and point with your right finger on the touchpad. Selecting with the left thumb works well.But we are far away from seamless integration of these kinds of peripherals with TVs. Samsung did a better job of accommodating an external keypad and mouse than Sony (I have not been able to get a keyboard to work with a brand new Sony at work). But the keyboard doesn't work with the 3rd party apps. Also, the touchpad is erratic for a minute or so after the TV is turned on. Perhaps other tasks are running.For the price, this is a good keyboard for this purpose, and perhaps the TV manufacturers will get their act together before Apple eats their lunch with a well integrated system that includes TVs (btw, the keypad works well with my macbook, even though its a windows-oriented keyboard).
Although not perfect, this keyboard fulfills its purpose well
August 1, 2012
For a while now, I've been wanting to purchase a nice, portable keyboard that will allow me to use our nice laptop paired with our LCD television. I took a chance on this keyboard and, for the most part, am not disappointed whatsoever with it. In fact, I am typing this very review using this set-up, and it is working quite well for that purpose so far. It's not a perfect set-up, by any means, but it is a very satisfactory solution for these circumstances.The keyboard is quite small and light-weight, making for an ideal keyboard for portable, couch-surfing computer use. Its small size also makes it very easy to store the keyboard in a drawer when not in use, which I like because it keeps my home less cluttered. You have a little touchpad built-in, which is very convenient if you don't want to fiddle with a portable mouse and keyboard. There is a very nice button in the top left of the keyboard that acts as a second left-side mouse-button, so you can use your left thumb in combination with your right hand with smooth, intuitive results. It's great for that. The keyboard is clearly designed with this sort of set-up, that is to say, relaxed computer use on your TV, and it really fits the bill almost perfectly for it. The usb plug-in ranges from very small for your laptop, to normal usb keyboard plug-in size for your large desk-top. I use the smaller one and it works well and is hardly noticeable on my laptop. There's a switch to turn the keyboard off to conserve battery-life, and I really like that myself. It helps keep the already-decent battery life preserved even longer.It's not all perfect, however. For one, the connection can be a bit spotty. It seems that if there is anything in the way between the laptop and the keyboard, the signal is messed up and mouse movement and keyboard typing becomes erratic and virtually useless. This happens even if I'm less than five feet away from the laptop! Moving the keyboard a little bit to be more in line with the computer usually does the trick. The keyboard itself is fine, but will take some getting used to. To fit a full keyboard AND a touchpad on an already smaller-than-normal platform makes for a very cramp keyboard indeed. Having smaller-than-usual keys is tricky enough, but even keys such as shift and tab are a lot smaller, about the same size as normal letters, and this takes a lot of time adjusting to. It can be a real pain at first, trust me. There's no indicator on the keyboard that says whether caps-lock is on, or how much power is on, which is quite unfortunate.I've owned this keyboard for roughly 4-6 weeks now and have acclimated to using it fairly well by now. I waited this long so that I could write an honest assessment of the product without the blush of excitement of using my laptop comfortably on the TV, or the blush of irritation as I struggled to get used to it. Writing a review like this back then would have been nearly impossible due to the different size/set-up of a standard keyboard, but now it feels like second-nature. All-in-all, I'd definitely recommend this keyboard to all who are looking for a way to relax in the living room while using the computer, or who are looking for a convenient way to use your large-screen TV as your monitor. It's definitely a nice piece of tech to have. I hope this review was helpful. Thanks for reading. Toodles.
Perfect fit for internet connected TV
July 16, 2012
I bought the Logitech keyboard to use with my new Samsung UN46ES6150F LCD TV. The television is internet connected with a web browser, but trying to type anything using the arrow keys on the included remote was terrible! So, I did a little research (very little) and quickly ordered the keyboard.The keyboard is almost full size with nice keys. Very tactile with great feedback. The touchpad is quite large and responsive. The keyboard is NOT bluetooth and comes with its own USB dongle (and batteries!). I plugged the dongle in the back of the TV and it immediately recognized the keyboard. What a difference....typing and navigating on the TV now is a breeze! I walked into an adjacent room to test the range and even at around 25 feet or so...no problems.I'm happy with it.UPDATE (7/19/2012): The keyboard is not bluetooth. It does come with it's own dongle, and you must use it. You will not be able to pair the keyboard with another bluetooth device. It will only communicate with the USB dongle included.UPDATE (10/10/2013): Added the "NOT" in front of "bluetooth" above.
A solid value (Mac compatible, too -- with some caveats)
September 8, 2011
Although there are a lot of promising ways to enjoy online content (web browsing, YouTube, Netflix, etc.) on your TV, the best one I've found so far is ... a computer.The Logitech K400 is clearly designed with this setup in mind, giving you full control of a computer in a couch-friendly form factor. Surprisingly, it seems to be one of the few such input devices with a (near) full-size keyboard instead of a tiny thumb-sized one. Obviously, that means it's much larger than a conventional remote control, but it's also much more usable. It looked like exactly what I wanted, and at a reasonable price, too.The K400 features a fairly attractive, clean design (aside from the odd "random lines" artwork on the trackpad). It's much lighter than I expected, which is nice, but it's also not incredibly sturdy. The build quality is fair for the price, I'd say, but doesn't seem likely to withstand a lot of abuse.As long as you don't plan on writing a novel on your TV, the slightly-smaller-than-full-size keys are pretty usable. They aren't backlit, though, which would be especially useful in a dark living room. On a semi-related note, the Caps Lock key doesn't light up, either ... but you don't use that key anyway, right?One very handy feature is the additional left-click button in the upper left corner, which lets you operate the trackpad with both hands or thumbs. It's a lot easier to click or drag with your left hand as you move the cursor with your right hand this way. The trackpad also conveniently offers Mac-style two-finger scrolling.Other nice touches include an on/off switch, and a slot behind the battery door to stow the teeny tiny USB receiver dongle. It also ships with factory-installed AA batteries, which is always appreciated.If you're looking for a decent keyboard for a home theater PC, this one seems hard to beat -- especially for the price!--About Mac compatibilityThe keyboard claims to support Windows only, but I suspected this wasn't the full story. Sure enough, when I plugged it into a Mac, the keyboard and trackpad worked automatically -- complete with two-finger scrolling -- on both Snow Leopard and Lion. Even the volume buttons are functional (but not the semi-pointless "home" button, it seems).OS X identifies the trackpad as a mouse, so that's the preference pane where you can configure the sensitivity of the tracking and scrolling gestures. The latter really needs to be dialed down to work well, in my experience. Also, you may want to remap the Windows (Command) and Alt (Option) modifier keys for a more Mac-like layout.The only catch? I can't figure out how to disable tap-to-click on the trackpad. (I'm hoping a software hack will make this possible, and that it's not hard-wired into the device itself.) Unfortunately, Logitech's Control Center software doesn't recognize the device, either.If you can live with that, the keyboard otherwise works just fine with a Mac, despite the official word from Logitech.

I like almost everything
October 8, 2017
I like almost everything. It worked right out of the box. Wonderful! Its shortcomings are, the # sign is NOT the "upper case" 3. What is typed is the English currency pound sign. Was this keyboard made for England??? Another caveat is the @ sign. The @ sign is NOT the "upper case" 2. And, then it stands to reason, " (quote) is not on the keyboard next to the ENTER key.1. I figured out the @ and " were interchangeable. So when I am typing an e-mail address I use the " key, and when using quotes, I use the upper case 2.2. The # sign was ALL TOGETHER different. I was going to return the keyboard because I use lots and lots of # signs. I ACCIDENTLlY came accross the #. It was the back slash!!!!3. So where is the back slash???? Can someone help?? I don't want to return because I know this "happened" on three of these brand new boards. So it definitely is the board. Is there a way to change, is there a way to program and F key for the back slash (if I can find out where it is...)4. I will be calling the company tomorrow, wish me luck.
Works with Ubuntu 17.04 Linux, good value for the $
September 23, 2017
Works well with Ubuntu 17.04 once I installed the Solaar package. Otherwise only the mouse was paired with the unifying receiver. Solarr lets you pair multiple devices. It's available on github (posting a link here is not allowed). Keys are OK for an inexpensive non-mechanical keyboard. I would not do a lot of writing or programming but for casual use it is OK. Mouse is actually pretty good;: it even mostly works on glass (1/4", bottom surface frosted) but works better on paper or fabric. For the price, it's hard to beat.
Good K&M combo for the average user in the average home
June 19, 2017
I used to have a huge wireless keyboard and mouse (also by logitech). Had it for a few years, but it started to get crudded up. I tried to clean it myself, but then saw that this was available for cheap so I decided to get it. I like that it's light and fairly quiet. Seems pretty resistant to dust and dirt and crumbs so far. Not crazy about the small size of the mouse, though. This is like a kid's mouse. I need something that fits an adult hand (and I dont even have that big of a hand!).Not the greatest K&M combo in the world, but good for home use and the price is right.
Good, but...
April 20, 2017
This mouse uses a 2.4ghz signal. The same as a home wifi network. In our apartment building, there are a lot of competing signals and the mouse keeps being cut off. We have it hooked to my dad's Chromebox that he has hooked to the tv and uses from across the living room, so it's 10-15 feet away. It may work better if we'd use it for a computer right on the desk. The keyboard works wonderfully, though. I just bought a bluetooth mouse to replace this one and we aren't having any problems. I don't think there is anything wrong with the mouse, other than that it has the weakest signal.
Best keyboard for the price.

This is the best keyboard ever since it is so simple and cheap. Don't care for the mouse. I like my Logitech MX Master. The Logitech MX Master can work on either Bluetooth or a Logitech Unifying receiver. The downside with this keyboard is that it has a proprietary USB dongle that only works with this keyboard. It seems like with the Bluetooth technology we have today that my MacBook Pro's Bluetooth antenna should be able to handle a simple keyboard. I like bluetooth only devices because my laptop only has 2 USB ports and when I bring it to work I don't want to have to plug a million things into it. I have my external monitor and my USB dongle for this keyboard. The bluetooth only keyboards that I have seen available are more designed for travel use and have weird layouts of the keys. The layout on this keyboard is perfect for my needs and is easy to type on, so I can't move on to anything else yet.
Great value for OK equipment
January 4, 2016
At $19 with batteries included this is a great value. The keyboard feels OK. It has an ON/OFF switch, but does not have an indicator light to show that it is ON. A light might help me remember to turn it off to save battery. It worked reliably from 30 feet away.The M185 mouse is OK. It's significantly lighter than my old Logitech M305 mouse, and has smooth plastic sides where the M305 has nice grippy sides. This M185 mouse has an On/Off switch, but has no indicator light on top, and the motion tracker on the bottom seems to use light outside my range of vision.It hasn't been an issue for me, but it seems like it might have been nicer if the keyboard and the mouse used the same size batteries. The Keyboard uses two AAA, the mouse uses one AA battery.

Cramped keyboard, but it's a cheap alternative for Mac users.
September 5, 2015
This keyboard is tiny and hard to get used to. The Shift and Enter keys are about half the size of those on regular keyboards, so pay close attention when first using it. I'm using this keyboard/mouse on a Mac, which it says you can't do but totally can. My rating is based on how small and cramped the keyboard is, regardless of Mac functionality.I use a Macbook Pro Retina (Late 2013) and had no problem installing the keyboard. I just plugged in the mini USB transmitter and turned the keyboard on. My Mac gave me an error and said the device wasn't recognized, but I'm typing this review on the keyboard. When you're done using it, the battery compartment has a spot to hold the dongle.If you want to use this keyboard with your Mac, here are a few things to note. Both the trackpad and keyboard work fine. The trackpad is a bit touchy. You'll definitely have to play with the speed setting until you find the sweet spot. The pad responds to moving the cursor with one finger and allows for a two-finger touch to bring up the right-click menu. All other mouse functions you expect on a Mac are disabled.As far as the keys, the layout is cramped. The shift button is the same size as the letter keys, which is hard to use. For Mac users, the Windows button (the 4 squares) is your Command button. The media player (pause/play, next track, previous track) hotkeys and volume hotkeys at the top worked just fine, as does the Alt button. Other than that, nothing else corresponds correctly. For example, pressing the F1 key in your browser is the "Add Bookmark" shortcut. F2 and F3 do nothing. F4 closes the window you were using. F6 depicts the gear symbol commonly associated with Settings, but when pressed in Safari it closed the window and opened up a new email with a link and screenshot of the page I had been browsing.There are 5 keys at the top right that also don't do anything special for Mac users. The round button with the mouse icon can be held down while dragging one finger over the trackpad to highlight text. The music icon and home button do nothing. The PC button with the padlock symbol, when pressed in Safari, highlights the browser bar so that you can type in a new web address. The PC power key does nothing.Overall, it's okay for the price. I certainly wasn't willing to spend over $100 for a Mac keyboard and additional trackpad. Just prepare to spend a long time getting used to the keyboard. It's been a week and I still find myself getting frustrated and using my Mac's trackpad or keyboard instead.
kinda good
December 10, 2014
This wireless keyboard I thought would be great fit since I have to change out the batteries on my logitech board and mouse however the two of them are two completely different types. This board was very small since I'm a large guy with very big fingers as I like to call them sausage fingers.prosyou don't have to change out two different types of batteries.does have one interesting feature that shuts down my computer at a touch of a button.the mouse pad aspect of the keyboard does have a zoom in and out feature.you can hide the keyboard receiver in the keyboard itself.consThis was again far too small for me to typethe mouse pad part was buggy and sensitive.the keyboard drains out the battery lifethe on and off switch was hard to moveso in the long run if I need a wireless keyboard and mouse for a short period of time this one will have to do but only in a pinch. If you looking for a good keyboard don't think about this one.
Old-timers taught on old typewrites will probably HATE this keyboard. I learned to type in 1963 and this keyboard is ZERO for me
December 7, 2014
This keyboard is OKAY, if you haven't had 50 years of training with bigger shift keys. I first learned to type on typewriters in 1963, during the summer after my sixth grade year, and my training HATES this keyboard.Enlarge this picture and look at it. The right hand shift key is half the width that it is on your typewriter. Where the left side of that key is on most computers and on all typewriters (that I know of) is an up arrow key, part of the four arrow keys usually off to the right of the Enter/Shift/Ctrl keys.If you have had too many years of training with typing on older keyboards, you may end up hating this keyboard. Amazon has refunded my money, and even offered to pay the shipping back to them, since the SHIFT key cannot be fixed. I have ordered the Kensington keyboard instead, a wired keyboard with bigger keys, and better separation between keys so I'm less likely to hit double-keys, especially between the "A" and the "Caps Lock" key which I'm always double-bumping on my ACER keyboard, which is why I tried ordering this, and then the Kensington, keyboard.The touchpad is nice, but I'll go back to my mouse.
I'm surprised that Logitech didn't do better on this model !
September 13, 2014
I wanted to love this but and the keyboard being smaller isn't the issue because I have small hands. It's just that in order to be accurate with this keyboard: you need to learn different placement of a few keys (smaller keys - like the right hand 'shift' key) and a person has to watch themselves type. It's hard to get a 'feel' for few key-placement-changes on this keyboard.It's also very light-weight and in my humble opinion not up to the usual Logitech quality. Unfortunately; as I'm developing arthritis in my wrists and hands......I'll need to become used to a keyboard like this. I just hope Logitech comes out with a better - heavier weight - model. Over the years I've owned many Logitech mice and keyboards......and loved them! Just not this one.Not sure if I'd recommend this. Seems like it needs more work at the design level. Thank you.
Right Shift Key - meh
May 14, 2013
I use this keyboard to write/edit word documents on my Galaxy S3. I use the keyboard far less than I'd hoped simply because of the right shift key. It's very small, and usually when I'm speed-typing, I hit the up arrow instead, which is in the area that a normal shift key would take up.It's not a BAD keyboard - it's just a nuance that you need to seriously consider before you make the purchase. Depending on your circumstances, this may not be a problem for you. (I can't think of a scenario where a person would be shopping for a keyboard and NOT need the shift key to work properly, but to each his or her own....) As a writer, I can't deal with it. It's now my back-up keyboard and it sits out in my suv for travel 'emergencies'.The trackpad works great, the buttons are great; everything is great overall - better than great - except for the shift key.Blasted shift key....
Technically great but practically a bad layout for certain typists
April 20, 2012
My Usage: I purchased this for use with my PS3. It seemed like a decent choice since it had wireless and also a touch pad attached which would spare me from having to awkwardly try to use a mouse on my sofa when needed. My primary desktop keyboard's spacebar ended up choking with a deadline approaching the next day so I had to resort to using this mini keyboard as my primary. This is my story.The GOOD: The keyboard just works, instantly, after connecting the USB transmitter. No drivers necessary, no binding processes. You just plug in the USB piece and everything is good to go, batteries'n all. Great looking on screen display for functional buttons like audio and caps lock too. Logitech really knows how to streamline this processes.The BAD: I can't fault the product from a technical side, nothing is really broken... except the layout. And really all i'm talking about is the shortened right shift button that destroys my productivity on this keyboard. If you are a person who uses the right shift instead of the left shift (I really don't know what the general population uses) then you will likely find it very frustrating that whenever you try to hit the right shift you end up hitting the up arrow instead. On just about any full size or laptop keyboard, the right shift button is at least as long as the Enter button above it. On the Logitech, however, the shift is cut in half and shares real estate with the up arrow. I would have much preferred the arrow keys placed under the touch pad buttons than in its current location. I know this may sound like a nit pick since it was not meant to be a full keyboard but if you are a fairly fluid typist this may very well throw a larger wrench in your WPM than you may have expected. Be warned.

Good Keyboard - Lousy Mouse
October 6, 2017
As expected, based on the price, the keyboard and mouse are both lightweight and cheap. However, I like the feel of the keyboard. It's keys are more "old school", which I definitely prefer over the lower profile types. The mouse is pretty poor, though. The plastic edges of the lighter color band wrapping around the top of the mouse can be felt, so it doesn't feel smooth in the hand and will certainly pick up hand grime. The roller indents are not quite solid enough. The sensor is too sensitive, so that when I pick the mouse up to reposition it the screen pointer moves more than my old Logitech mouse so I have to pick it up higher before putting it back down. Worse, the sensor seems to be slightly misaligned compared to other Logitech mouses I've owned, so that it wants to move at a slight angle when I move it straight up. Again, I've had several other Logitech mouses and never had a problem. I purchased two of these MK270 units and the problems are the same on both. Lastly, the two that I received did NOT come with the unifying receiver. I've decided not to send both back because of this (although I AM sending one back because the keyboard itself was defective). Because I like the keyboard so much, I'm going to keep it and use it alongside an old Logitech mouse and deal with two dongles.
this is an excellent buy for notebook users who have to work long ...
August 8, 2017
Reliable and well shaped. Would have graded it higher, but the keys are somewhat stiff with too high a travel--typing is work, compared to the Microsoft keyboard, for example. But the price is right, and having the separate input devices increased the useability of my notebook over a full workday enormously from an ergonomic viewpoint, especially in tandem with a standing desk. If you can live with the harder keys. this is an excellent buy for notebook users who have to work long hours, and a much cheaper alternative to a separate monitor--just elevate the computer to ideal eye height, and leave the keyboard and mouse on the desk.
Excellent keyboard; terrible mouse.
July 28, 2017
While the combined keyboard and mouse offered here at Amazon is a great deal (especially when I picked it up as a part of a PrimeDay Special), the keyboard itself is excellent while the mouse is a disappointment. The keyboard has a large, spacious layout with slightly textured keys. I absolutely love it. The feedback is perfect too. While I don't use the additional "shortcut" buttons on the very top of the keyboard, the on/off switch above the number pad is convenient and saves battery life. Other keyboards I've used in the past included a switch on the bottom, if at all.Again, the mouse is a disappointment however. It is both too small and ergonomically awkward to use for my slightly large, male hands. Scrolling with the center wheel stutters up and down documents and pages when browsing online instead of the smooth, natural scrolling of my former mouse. In all, it works to point-and-click around a screen but is more annoying than its worth. If your hands are tiny, this may work for you. Otherwise, purchase the keyboard separately and look elsewhere for a mouse.
Received non-Unifying version; interference(?) issues made it unusable
April 15, 2017
I was satisfied with the build quality of both pieces of this set (as expected given experience using Logitech products over the years); I received the non-Unifying-receiver version and experienced what seemed to be interference (I work in an office with numerous wireless devices operating on various frequencies). Could potentially also have been a power issue as it sometimes seemed one or both units would power down or enter a sleep mode; fresh batteries did not change this nor could I discover any setting that would affect it. I reluctantly returned this. I suspect the Unifying version would work for me as I subsequently began using a Logitech mouse with Unifying receiver and have experienced no issues.
mouse great, keyboard great when it works, irritating when it doesn't
August 25, 2016
I really wanted to like this, but I frequently have the same problems some others have reported with this keyboard. It really lags sometimes.In other words, I type in a few characters (doesn't matter which application, same behavior in Word, Firefox, Notepad, etc) and then wait several seconds for the letters to show up on the screen.The mouse works great, even when the keyboard isn't doing so well.The fact that the mouse keeps working while the keyboard lags, combined with the observation that the keyboard sometimes gets a lot better after I turn it off/on, leads me to believe that this is most likely not a wireless conflict with my 2.4 Ghz wireless USB interface. I think it's just a problem keyboard.Update: I used a USB extension to put the USB connector closer to the keyboard and have had no problems since. Updating to 3 stars.
Great keyboard, mouse failed at 8 months
January 25, 2015
I love this mouse and keyboard combo. The keys are soft-touch and low-profile, so my wrists don't hurt after hours of use. My only complaint is that sometimes the mouse's scroll-wheel just.. doesn't work. It rolls, but the computer doesn't think it's doing anything. This has happened while browsing the web, in Office applications, and most notably in video games. Sometimes it starts working again on its own, and sometimes I have to restart the software or reboot the computer. Very intermittent but weird. I've never had this issue with Logitech wireless mice, so not sure if mine is just a dud. I still love this combo though, the issue isn't serious enough to warrant a return.Update at 8 months: The mouse's scroll-wheel continued to randomly stop working, and then the mouse started failing entirely. I replaced the batteries so that's not the issue.. it just stopped working. Turning it off and on again fixed the issue a couple of times, but now it doesn't work at all. I have another logitech wireless mouse (stand alone) that has been working for far longer, so I don't know if this is just an issue with the combo mouse or if I just got a dud.

Very Annoying On a Mac
January 9, 2015
You can temporarily disable the Tap To Click and Swipe gestures by clicking each mouse button while the function key is depressed, but it resets not only every time you turn the keyboard off, but also after so many hours (5 or 6?). And make no mistake. If you use this, on a Mac at least, you will want this feature disabled. It is terrible. The tap to click function on this keyboard is completely unusable. It is crazy sensitive, and you will constantly select things on accident. Worst yet is that the default swipe gesture will delete anything selected if you swipe from one side of the track pad to the next. You will inadvertently delete things. I guarantee it. I deleted an iTunes playlist within the first five minutes of using this keyboard. There is no 'undo' option for deleting a playlist in itunes. I had to recover it from a backup. I have since tried everything under the sun to disable these gestures from within OSX: I. Can. Not. Disable. The. Wretched. Tap. To. Click. And, I spent a lot of time trying.I love everything else about this keyboard though. Gets a way better signal than the bluetooth crap the mac wireless keyboards/mice use. If you get in the habit of manually disabling the gestures every time you turn the keyboard off it's a nice keyboard- especially for the price. If anyone reading this has permanently disabled the trackpad gestures please correct me. (I tried half a dozen 3rd party programs and even tried altering system files, and I was not able to disable it.)
Finally! A keyboard that causes shame-tingles!
December 26, 2014
This is a wireless keyboard. Instead of a number pad, you get a non-clicky multi-mush trackpad with mush buttons that's about as accurate and precise as a Venus De Milo sculpted from of tapioca pudding. The nanosecond you place your finger on this trackpad, it's a toss of the dice as to whether or not it will correctly move your cursor in the desired direction, or send it shooting offscreen. Put a second finger on the trackpad, maybe it'll scroll, maybe it'll totally disregard your input.The keys are sharp and unpleasant to type on, like doing a handstand on Lego. Do you like using the right shift key? Fuhgeddaboutit! Instead you're going to hit an arrow key sending your cursor off the intended path where your typing will resume just about wherever else you didn't intend for it to.The use of the arrow keys require the kind of strange contortion/Riverdance that you only find yourself doing while trying to exit the Men's room at a dive bar at the same time another guy is trying to do while an emergent vomit is coming on.I'm not sure what the wireless range is supposed to be on this thing, but I'm pretty sure that 5 feet-line-of-sight might be asking a bit much, as it will drop characters if the slightest occlusion is introduced.The whole experience of using this keyboard is not something you'd ever want anyone else watching you do...it'll make you look like a nincompoop that can't type full words correctly or aim a mouse cursor at a large stationary target...You get those weird shame-tingles every time this device makes some bone-headed mistake on your behalf.On the plus side, it is wireless, lightweight, takes regular ol' AA batteries and is not too gaudy as to keep out in plain view. It just doesn't seem like it was designed to actually be used by human beings.
Limited Range and Spotty Performance
August 10, 2014
Keyboard works, but has limited range. My media-pc (laptop) is about 8-10 feet from my couch in the living room. I tired moving things around and it still doesn't work consistently. We have a small hand-held keyboard/mouse (like a remote - also bought on Amazon) which works awesome, but the keyboard is not the best if you need to type more than a URL or web search. The range on the $14 hand-held device is great.This was to be the solution for the keyboard, but alas... this is not the solution. There is a delay when typing and the trackpad doesn't move where you tell it when you are at the limit of the range. If I put the keyboard on my coffee table it works semi-consistently. Though, if I want to be sitting back on my couch with the keyboard.. no dice.Very disappointed--I expected more from Logitech.
Extremely bad shift key placement
June 29, 2014
(Original review 6/29) I didn't notice on the picture, because it never occurred to me to look for such a thing, that the "up" button is BETWEEN the question mark and the right-hand SHIFT key. Holy mother of god. Whenever I want to use the right shift key, which is far more often than the left because the QWERTY system is designed to have the most common keys on the left side, I have to reach OVER the up button (so far I'm mostly just accidentally hitting the up button instead and then having to go back and fix). I can't decide whether this keyboard was designed by someone who was a non-typist, or just someone with much bigger hands than mine. (edit:) NO TOUCH-TYPIST WOULD BE ABLE TO USE THIS KEYBOARD.Guess I should have read the negative reviews more carefully.(Addition 7/15) I liked the size (not a mini, but still small enough not to take up a lot of room on my desk) and the responsiveness of the touchpad. I just couldn't get past the shift key problem. Maybe there's a way to remap the keys just for this keyboard through SetPoint, but another problem is that SetPoint doesn't work with Windows 8.1. (I called Logitech. They blame Microsoft.) I tried remapping the keys through SmartKeys, but the problem with that is the remapping is not specific to this keyboard, so if I take the computer somewhere else (on the road, or even to the couch) and want to use the native keyboard, I have to undo the swap each time. Not a good solution. I have no choice but to return the K400.Nothing else in this price range looked any good either, so I broke down and spent $$ on the K830. So far, so good; I will review it on its own page after I've had a couple of days to spend with it.
Not for me... typing not very comfortable, Touchpad not very useful
February 22, 2014
Whenever I read one and two star reviews, I keep in mind that they are written from the user's perspective and I may or may not agree with their preferences. I'm pretty sure my review also falls into the same category. This feedback is based on my preferences and experience. Hope it helps users who share the same perspective.I bought this keyboard to use it on a daily basis with my laptop. I tried it for a few days and following are my likes and dislikes about the keyboard.Like: - The USB transmitter that should be connected to the laptop is compact and almost invisibleDislikes: - The size of the keyboard is a little too small for regular use - The keys are too close to each other and hence result in clicking the wrong keys quite often. Please note that I'm quite comfortable using virtual keyboards on iPads, iPhones and other compact devices. So it is not that I have a general issue with small keyboards. It is just that this one does not seem to be the right configuration for me - As a consequence of the above point, my fingers used to hurt after using the keyboard continuously for even an hour - The "shift" key on the right side of the keyboard is less than half the size of the one seen on most normal size keyboards. The "up" arrow key is located right next to this "shift" key and half the times I end up clicking these two keys at the same time that results in highlighting the text on the current line and the line above. So when I press another key that was intended to be pressed along with the "shift" key, it replaces the entire highlighted text with this one (the most common issue I was running into, with this was when trying to get a `?') - The touchpad is too sensitive to touch. While scrolling, if the fingers reach the edge of the touchpad and need to be replaced inside again to continue scrolling, when lifted and put back on the pad, it registers a left click. However lightly I tried to put my fingers back on the touchpad, stuff was getting selected/highlighted/clicked - Since most 5 star reviews I read mentioned using this keyboard with a TV, I tried to do that as well but did not find it very useful there either. It is not small enough to hold in two hands while typing. The keyboard needs to rest on something which means, it cannot comfortably be used while lying down in bed (or even partially lying). I find the smart TV remotes with full QWERTY keyboards or a mobile device like a phone/iPod to be a lot more convenient for this scenario - My personal laptop is a Mac and I'm quite comfortable with the Mac's Touchpad. Though some of the multi-touch gestures on this keyboard are similar to the Mac and useful, registering a click when touched even lightly, makes it almost unusable at least 50% of the time. I know the keyboard does not say it supports Mac and this particular drawback is not taken into consideration for my 2 star rating. I'm indicating this just in case someone planning to use this with a Mac reads this review and finds it helpfulIn case someone is wondering why I gave 2 stars instead of 1, 1 is "I hate it" and 2 is "I don't like it. I don't really hate this keyboard, just didn't like it :-).Bottom line - based on my personal preferences and experience, this was not the keyboard for me. I'm sending it back to Amazon and this is the first product I bought from Amazon that I'm returning.
Right shift is a deal breaker
October 2, 2012
I read a few reviews on this keyboard before making the purchase. I used it for a day at work and a bit at home. The keys feel good, and it's convenient to have the touchpad on the keyboard. I was very interested in having the touchpad on the keyboard.Sadly, the right shift key being 1/2 normal size with the pageup taking the left half of the normal shift key caused all sorts of problems. Could you get used to it? I thought I could, but no way. I thought it wouldn't be a big deal, but it seriously drove me nuts. Even my 13 year old daughter commented on it, and she's not a super fast touch-typer.I'm spend many hours per day on my keyboard, whether it's my cheap-o Microsoft 2000 wired board, the one on my macbook, or something else, I've never had this much trouble adjusting to a keyboard. Now this brand new keyboard sits in storage. Maybe it'll be revived when I build another media center machine and won't be doing much serious typing.

MK 270 -- not unifying receiver
August 22, 2017
As a previous reviewer noted, there are two versions of the mk 270. This was listed as being a unifying receiever model, but I received a nano receiver that is not a unifying receiver. Since I don't have other logitech products I'm trying to sync, I don't care too much, but this is not how the listing advertising this product.That being said, the product seems to work pretty well -- the keyboard is decent for a $20 keyboard, the mouse is a little small but works, set up was painless, etc. Worked well with my cranky old desktop upgraded to W10 last year.
Bah, humbug.
August 22, 2017
The mouse works fine, the keyboard is iffy. Some keys seem to work all the time, others are pretty spotty, and the direction arrow keys simply quit for no apparent reason whatsoever. Until they come back on for no apparent reason whatsoever. I've used Logitech for ...it seems like decades... and have never had a problem until now. (So of course I threw away the box... because I'm a dork.) So ... it's mine now until I buy another... soon...and then it's off to my growing pile of electronic recycling. Bah, humbug.
I will say that the mouse and keyboard work well and feel sturdy enough, especially for the price
April 25, 2017
It was hard to finalize a rating for this product for a number of reasons, because for some people it might be worth 5 stars, but I'll briefly explain why it's only worth 2 to me.First, I will say that the mouse and keyboard work well and feel sturdy enough, especially for the price. My main two issues though can be summed up by the fact that the product listing is misleading and in fact incorrect.Issue 1 - The mouse is better suited for travel and is definitely not full size. This was never mentioned in the listing and might steer people elsewhere for this type of purchase, especially when buyers are specifically looking for full sized 9 key keyboards as a pairing.Issue 2 - The main reason I settled on this combo unit is because it was represented as containing a Logitech Unifying Receiver, which it clearly does not. This is a deal breaker for me and will cause me to return this product.
Poor connection, keyboard freezes and keys stop working.
February 3, 2015
My wife purchased the Logitech Wireless Combo Mk520 With Keyboard and Mouse for her home office, and loves it. I needed a keyboard/mouse combo for work, so I purchased the MK270, a cheaper version. Well, it is definitely cheap. The keyboard has frozen mid-typing, the backspace, delete, and arrow keys have a tendency to stop working as well. I changed the batteries and even relocated the PC tower so that the USB transmitter is in line-of-sight with the keyboard - still having issues. It's cheap, only $20, but I am considering returning it.
Keyboard to Computer Delay
August 4, 2014
Updated Review (8/18/2014) - I cannot stand the delay from the keyboard to computer. I have officially snapped and will not be using or recommending this product due to the delay. I keep my keyboard off when I'm not using it (when the computer is off and I'm not at my desk) but when I don't type on it for a minute and go to type, I expect it to type, not delay 20 seconds and still not use all the letters I typed in. It might start working after 45 seconds of frustration and wearing patience.Original Post (8/4/2014) - 3 Stars: I absolutely hate the delay from the keyboard to the computer. Sometimes it's sporadic but can take up to 20 seconds before it catches up. I am considering going to a wired keyboard or trying a different one because of how frustrating this is. I've only been using the keyboard for about a week and a half.
Be aware - two different versions out there
March 28, 2014
I ordered it on 3/23 from Amazon and received a couple of days later. To my surprise, the box doesn't say "unifying receiver". Took the keyboard/mouse out - yes indeed the receiver only says "Nano Receiver", and it doesn't have the orange star unifying logo. I also installed Logitech Unifying software but this receiver is not recognized.UPC/Product ID all match. Appears Logitech changed the product. Amazon needs to change the product description.If you are looking for a unifying receiver to work with other logitech products, don't buy this.Update - Amazon sent me a replacement, and this time it comes with Unifying receiver. UPC and product ID printed on the boxes are identical, packagings are slightly different. One has "Unifying receiver" clearly printed on the box and feature list and the other one doesn't.http://www.amazon.com/gp/customer-media/product-gallery/B00BP5KOPA/ref=cm_cr_dp_cust_img_see_all_img0Keyboards and mice are also different. One set both have orange star unifying on the label and the other set don't. Product IDs are different too.

... twice when I first got it and it seemed fine. I just now went to use it again ...
December 1, 2016
I've used this keyboard maybe once or twice when I first got it and it seemed fine. I just now went to use it again and it no longer is detected as being connected, thus it doesn't work. I came on here to hopefully process a return or exchange and apparently it has a 30 day return limit that has passed by a couple weeks. It appears I have to do a warranty claim which Logitech (which I just filled out), and my first impression is that it appears their CS is going to be absolutely awful. I just filled out a claim and it doesn't even allow you to talk to anyone and just shows as unresolved after I filled it out. Now I can't even find the submission after closing the window and logging back into my account, so I'm hoping it's even handled....regardless, it's a terrible first impression.

If you know how to type, don't use this keyboard. Only a two-finger typist will find it useful. The misplaced shift key makes it impossible to type as serious workers do.Cheap it is but it’s awful. Don't waste your money on it.The touch pad works erratically, causing you a lot of unwanted commands while you travel the pointer across the screen. I almost burst while using mine. I have to return it.I wouldn't recommended to anybody.This is the worse keyboard I ever bought.
This is a terrible keyboard - don't buy it
December 29, 2014
This is a terrible keyboard - don't buy it. If you touch type, the shift key on the right side of the keyboard is one third the size of the shift key on the left side which is standard size and is buried in the 4 arrow keys. Most of the time when I go to touch the shift key, I touch the page up key and the curser moves to the beginning of what I am typing. I've ordered the larger Logitech keyboard and this one is headed for the trash.
Until there is an update to the firmware or software, do not waste your money.

Even after setting all sensitivities to off or their lowest possibility, the track pad registers the slightest tap as a click, which is a problem when in email or looking at files, as these can become deleted without intent. Icons get moved when not intended, ads get clicked on webpages when just scrolling, etc. It is unfortunate, as the keyboard is a good size for my purposes. There are many complaints on Logitech's forums regarding this particular model. Until some manner of firmware or software update addresses this issue, I can only give this model 1 star (as I cannot give it less) and will let my toddler use it as a toy. After 2 months I have reverted to cabled mouse and keyboard. Sadness. Do not waste your money. Should there be an update and the trackpad oversensitivity resolved, I will gladly change my rating and update my review.
Changed my review after Amazon completely changed the product! Avoid the K400R!
December 5, 2012
YOU ARE NOW BEING SOLD A DIFFERENT PRODUCT THAN DESCRIBED.The white screenshot is the K400r, the black screenshot is the K400. Notice how the original K400 has useful volume buttons, and doesn't screw up for Function buttons.ORIGINAL K400: Loved this thing. Needs 1-2 battery changes per year (Amazing). Gets thrown around a lot, has had a liquid spill or two, still works like a champ. No pesky fn buttons to bother with.K400r (What you're actually being sold): Completely different keyboard. It's literally a different product, and it needs to be separated as so. It was made for windows 8. Has useless media buttons on top now (Lock, Music, and Home), and has more issues connecting than my original K400 did. Pesky fn buttons that prioritize lame media buttons over my Function (F2, F11, F5) buttons. The USB dongle's plastic top ripped right off as well. Not happy with the K400r. It's a different keyboard, so they get a different review.I'm obviously upset that I can't deploy the original K400 now. It's a better product that deserved a 5/5.I will update this review once Amazon depreciates the K400 product name and changes it to K400R.

Cheap piece of junk, mouse didn't work at setup, right-click doesn't work to copy and paste
June 12, 2017
This is a cheap piece of junk. The keyboard feels cheap, but that was not the issue. At installation, the mouse didn't work. After installing new batteries and other troubleshooting, I tried a different USB port and it finally connected. Should have worked in any of the ports. Biggest issue for me is the right click to copy and paste doesn't work MOST of the time - very frustrating. Mouse feels cheap too. Logged in to Amazon to return and see that I missed the return window by a few days. After reading reviews today, I see that there a lot of complaints that are very recent, like mine. Makes me think we all got counterfeit products. Irritated that I cannot return and get my money back.
11 months and 18 days of use and it stopped working
June 2, 2017
Simply disappointing: 11 months and 18 days of use and it simply stopped working.From good to dead and no; it is not the batteries.
Only worked for a few months
April 30, 2017
Oh the irony... here I am, trying to write this review of this product, while using this product and the keyboard stalls (as usual) and my words come out as a jumbled mess. I really wanted to like this keyboard/mouse combo, given the glowing reviews left by other customers. I bought it and it worked well for about three months, and then totally stopped working. OK, so maybe I got a lemon. I contacted customer service and they sent me a new one, no problem. Well, it's been one month and the new one is only working intermittently. Bummer. The words I type in don't appear for 10 seconds sometimes. When I move the mouse, it jumps and jerks around the screen, and it's hard to select what I want to click on. So while the keyboard and mouse both look and feel nice, they really don't work very well.You know what they say -- you get what you pay for! Wish I had spent my money on something more reliable/higher quality.
Keyboard cuts out- Poor Quality
April 11, 2017
Terrible. The mouse works fine, but the keyboard cuts out often. I'll be typing and suddenly, nothing's happening. Its not the computer as the mouse and applications continue to work. I use it daily and without fail, it stops working multiple times each day, sometimes for a few minutes at a time. It is incredibly frustrating, so much so that I dug my old wired keyboard out of the donate pile and am using that instead. Does not work consistently.
Don't buy.
March 15, 2017
The mouse has NEVER worked. I have contacted them numerous times, they give pages of instructions as if I have not already unplug, tried in new USBs, changed to new batteries, worked a couple days to get the keyboard before getting it to work. Weeks later and they still won't ship me a new one. I've worked with computer since 1976 probably longer than they have been alive. SAVE YOUR MONEY!, DON'T BUY
Mouse turns off at random
November 8, 2016
I am extremely disappointed. This is the first Logitech product I've used that I have not been satisfied with. I own a Logitech webcam, wireless keyboard/trackpad, speakers, and prior to purchasing this set, I had a wired Logitech keyboard and another wireless Logitech mouse. I purchased this set as a Gold Box deal to replace those (the tabs on the wired keyboard had broken off over the years, and the wireless mouse's dongle no longer worked).Initially, this set worked great. However, about a month ago, the following occurred:The mouse, even with a brand new Duracell Quantum battery in it (chosen as the Sweethome's #1 disposable battery) will occasionally turn off. The only way to make it function again is either A. take the battery out of of, put it back in; B. turn the mouse off and on again; or C, unplug the dongle and plug it back it. This is very frustrating, as this can happen several times across the span of a few minutes. It is too late to try to return this product, but I'm going to look into a refund and purchase a different Logitech keyboard/mouse combo.To reiterate, Logitech makes wonderful, high quality products. I believe I either got a defect, or this product altogether is not up to par.
