Carpal tunnel nevermore!
July 17, 2017
I never thought there would be a day where I would resort to an "old man" trackball style mouse. I got this because A. I was so tired of wires and B. I have carpal tunnel to some degree so the repetitive moving of a normal mouse would kill my wrist and forearms and C. Moving my wrist around so much on my desk always made my wrist red and painful. They send you regular batteries with this and according to the software I had about 500 days of use left before I needed to change them, what a breath of fresh air from those wireless devices that you have to change every few weeks or a month! I absolutely love this device and I must say that it has definitely made me reconsider the "old man" theory of using a trackball mouse. They are much more comfortable to use and much more effortless. Make the change today! From all of my research this appears to be the best wireless one available on the market today.
Best thumb trackball out there...
May 9, 2017
This model/design has withstood the test of time.
I still have one of the original, logitech thumb trackball corded model with the red ball. Works great.
It's been around forever and is ergonomic, durable - tough as nails, I have dropped mine a few dozen times and it still works like a champ.
I have about 4 or 5 of these floating around my home and office. The logitech unifying software is great - makes pairing easy.
The range is pretty good, I can control my laptop connected to my TV about 10 ft. away. When the battery is low or there is interference this tends to drop out, however. It's too bad they are not rechargeable - but the single AA battery lasts a REALLY long time.
By far the BEST advantage of this product - and really any trackball - is not needing a motion surface.
This is great for bringing along with your laptop and not getting stuck with the dreaded built-in trackpad; and you won't have to worry about a mouse pad or surface area for a traditional mouse.
A great iteration of the "thumb-ball" mouse
April 7, 2017
I grew up on the trackman stationary mouse concept since roughly two decades ago. Despite my attachment to wired peripheral devices, I have been very pleased with this iteration of the "thumb-ball" mouse. This is my gaming mouse and my everything mouse. The range was useable in the back of a 300 person classroom as a substitute clicker for a powerpoint presentation. With five separate buttons it fulfills all of my needs. I have stacked other wireless peripherals with little issue. One non-rechargeable Duracell AA battery lasts for enough months that I can't remember the last time I changed it.
The not as good:
Even at $27, this is a relatively expensive piece of equipment (could buy wireless K/M combo for that price). For new customers, the big advantage of this mouse is you can use it on your leg without issue if need be (like at an airport). However, the mouse is size-able and there is a learning curve for those who didn't grow up with it. If others want to use your desktop, this mouse can be a bit awkward...and for that reason if you gotta keep a spare "normal" mouse why would you buy this guy in the first place. Plus, unlike the modern laser/optical mice, you will need to take a few seconds to clean the trackball every now and then. Of the three Trackballs I own, only one of them is partially functional due to the left mouse button and some erratic pairing behavior. The three-year warranty allowed for a free replacement with the least headache of any computer peripheral company.
The "thumb-ball mice" will always have a place in my wallet. I'm very glad that this wireless version is just as rugged and user-friendly as I remember. Furthermore, the wireless capability has actually increased its functionality in my life and extended it to the modern age, where tangled wires have become less of a tolerable occurrence. Hopefully the clientele, old and new, will keep this technology alive for years to come.
Great product that can be made even greater with an angled stand
November 10, 2016
I've been a trackball user since the days before MP3s. This is my current favorite model. Affordable, reliable, cordless, and nicely shaped. I was using it so much that my arm started hurting until I realized I was using it at the wrong angle. I do 3d printing and designed a stand to make it even better and more ergonomic. I would highly recommend this product especially with a padded rest and angled stand like the one I made. You can find my stand at Thingiverse. [...] and make it yourself if you have a 3d printer. With or without the stand, this trackball is a great value.
A Thumb Trackballer
March 9, 2016
There are enough reviews here espousing the greatness of the M570 from Logitech, so I'm just going to briefly describe my experience.
I've had mine since 2010 and have been using it every day at work. I've found that, for productivity, it beats a mouse hands down. Over the years I have had absolutely no issues with this wireless trackball and it continues to perform flawlessly. The ball tracks smoothly and evenly. But as others have mentioned, you do have to give it a cleaning every month or so as the bearings tend to trap and accumulate gunk over time. The ball can also attract and have stuck to it the errant hair strand or lint glob that will cause the movement to feel gritty or stick and skip. It is easy to clean though. Pop out the ball, give the bearing a good wiping with a microfibre cloth (or other lint free cloth) and likewise with the ball, pop the ball back in and you're golden. I've probably changed the battery twice. The size is just about right for my hand (about 8.5 inches around at the knucles) and the contours felt natural from day one with my fingers aligning right in the groves, over the buttons, and my thumb placed just right on the ball.
I've ordered a second M570 to use with my tablet PC (MSI WindPad 110W). I'm currently using a Kingston Orbit. I tried the Orbit because it was smaller than the M570 (not by much though ... those product pictures sure are deceptive). But, I just cannot get used to the position of the trackball on the Orbit. I guess I'm a thumb guy and not a finger trackballer!
2017/03/17: Logitech, if you're reading any of this at all, please consider a G version of this! If the G900 Chaos can be wireless, then we can have a G version trackball. No need to deviate too much from the design, but a free-scrolling middle button, some more programmable buttons, a gaming sensor, a spiffy RGB LED layout to sync with the rest of the G stuff, even a removable cord for charging ... I'd go for that!

Better than expected. Never thought I'd ever like it..
August 7, 2017
The lazy part of me is really beginning to enjoy this trackball mouse. Never in my life have I every considered getting a trackball mouse. Be it as it may, the former Logitech M505 isn't left clicking as well as it used to; therefore, the trackball is a much needed replacement. Not moving my hand back and forth as well as speeding onto my secondary monitor has been a Godsend.After a single week of using it for the first time in my life, I am still adjusting to minute movements over URL links (small fonts..). My first use was for 8 hours without going back to my old mouse. I do wish the mouse was larger since my nearly 6' height also yields larger than average hands..Another small annoyance is that the ball seems to stick ever-so-slightly when it it sits for a while. Since keyboard shortcuts are primarily used, the trackball mouse tends to sit idle for most of the time; therefore, it sticks nearly every time I reach for the mouse again.
and it is excellent compared with a mouse
May 29, 2017
I have been using a Logitech trackball of this shape for years, and it is excellent compared with a mouse. The battery life is excellent and I can't even remember when I replaced it last. The three points on which the ball rests become dirty regularly, but are easily cleaned by removing the ball. The left mouse button on mine has probably worn out, and now double-clicks when I click it once, or sometimes doesn't click at all. This is why I'm here on Amazon looking at getting another, and only giving 4 stars. I was hoping to find a newer model, but this will have to do.
Warranty is for 3 years, and I don't know if I'm covered. The price here is much less than listed on the Logitech site, so not a big deal to pay for a new one. I know Logitech tests their products rigorously, but I doubt it will last too much longer than 5 years. The buttons are clearly the only part that is subject to wear and only one needs to fail requiring a replacement. I hope next time I need one there is an improved version with new button design.
Better alternative than a mouse
May 24, 2017
Good pointer device. I really like the wireless capability, allowing you to place it anywhere that's best suited for your workspace which is a real plus when working in a small space and raking a mouse around a desktop is not practical. I also like the natural position of the hand when using it. Battery life is very good when I remember to turn it off before I leave the office for the day/weekend. The battery indicating light on the top will let you know when the battery strength is getting low, alerting you to the fact you need to change it. The range of the trackball is good but I haven't tested it to find the limit. It works very well in the immediate vicinity of my laptop. The only area I would like to see changed is the ability to remove and clean the thumb ball. It feels, from time to time, the rolling elements might be getting dirty and would benefit from cleaning but there's no easy or good way to get to that area. Earlier corded models had a quarter turn bezel that kept the ball in place but could be removed for cleaning. I wish they still had that feature.
I am officially a trackball convert!
August 7, 2016
So far, so good. This was my first time working with a trackball and I didn't know if I would like it. I have been experiencing some pain in my wrist from the usage of mice while working and wanted a mouse that I didn't need to move about. This does the job quite well. I enjoy the size of it and I can rest my entire palm on it and work without worrying about accidentally moving the cursor across the screen when I shuffle about in my chair. It is very stable and doesn't wake my computer when my children bump up against my desk - something that used to happen all the time at my home office. It fits my hand and I took to the trackball concept very quickly. It took about 2 minutes to get used to it and I believe I'm hooked! I placed it on my old mouse pad and that has made using it easier since my wrist would otherwise be resting on the bare desk - which isn't terrible for short periods of work but 8 hours on a piece of solid wood and it starts to feel uncomfortable. I took one star away because the left click button seems to need an extra bit of push to maintain drag and drop operations. I noticed that if I try to quickly perform the motion the button releases mid swing and it has caused me to accidentally place files in the wrong directories when moving them. Other than that, a great product so far and I will be picking another one for the work office.
With a little help it is a GREAT solution for carpal tunnel and wrist pain
December 28, 2014
It's a good option for people with carpal tunnel such as myself and looking for a more ergonomic option. If it had a better angle out-of-the-box I'd give it 5 stars, however with a little propping it can be perfect, see below. Tips:1. To make it 10x more ergonomic, place a wedge with a 30 degree incline under it to make it the most natural wrist angle and keep you from resting any weight on the nerves in your wrist. Experiment with different angles to find the best for you personally. I trimmed a chunk of stiff foam from some laptop packaging material, see the attached photos. This has been a HUGE benefit for my wrists and in combination with other ergonomic tweaks to my setup and regular stretching and soft tissue work has left me pain-free for some time now.2. You'll need to clean the dust and lint from the rollers and optical sensor under the ball once a week, it takes seconds but will keep the trackball nice and responsive.

Awkward Use of Thumb
September 29, 2017
I purchased this mouse because of the reviews. I work in IT as a programmer and have issues with carpal tunnel syndrome due to repetitive motion and thought this would be a great help for that. However, I am returning the mouse because it just doesn't allow for fine detail movement using your thumb on the trackball. The scroll wheel and mouse buttons are fine. The feel is good under your palm, but it is very awkward to scroll with your thumb and try to hold down the buttons to capture the edges of screens and drag and drop etc. Maybe my thumb dexterity just isn't fine tuned enough but it's just not functional enough to be fast and I need to be fast in my job. I did download the management software from Logitech for the scroll ball mouse setup and tried several different settings but still not clean enough to be my everyday use for work mouse.
Mouse Works Fine but Software Connection Utilities are a Joke!
August 12, 2017
I have always liked the Logitech trackball and I like this one as well. It's basically the same as the T-BB18 trackball with some extras. The reason I only give it 3 stars is the connection utilities - in a word they suck! Oh, it eventually connects itself but it's a mystery to me whether the software that you download from Logitech has anything to do with it or not.The utility tells you it does not see any device and then, magically, it starts working even though the software still says it can't find a device.Pathetic! As long as the PC has been around you would think these companies could get it right at least once but it appears that users are doomed to be tortured for some years to come.
Only consider this if you can't use a normal mouse - it is much more difficult to use.
July 21, 2017
The quality and performance of the mouse is fine but the concept is a bit baffling. I bought it impulsively, based on the incredible reviews, thinking it must be great if that many people love it. However even after investing a good amount of time to try to acclimate to this, I find it infinitely more difficult to use than a normal mouse. It requires quite intense focus and fine motor skills to operate the track ball with your thumb - I find it tiring to use for that reason. Unless you have physical disabilities that make a normal mouse difficult or impossible to use, I can not see any value in this. I gave it 3 stars because I can't knock the product itself, just the concept, which still has value to people with disabilities.
Something is wrong with the design of this one...
June 24, 2017
I have a great deal of difficulty keeping this one connected to the Universal adapter, which is a problem I've never had with Logitech devices. I ordered a second one, thinking that perhaps the first was defective, and have had the same problem with both. If it doesn't have a direct line of sight to the universal adapter, or there is pretty much anything (like a coffee cup) between them, it works for awhile and then randomly stops until you pick it up and let it connect again. I will rearrange my desk to accommodate, but I've NEVER had to do that with any other Logitech device, and I use the brand almost exclusively. That means I also have multiple adapters available...I tried swapping them out, but it didn't make a difference, so it's not the adapter. I have the same problem at the office, with a different environment, different placement and a different model of keyboard sharing the connection, so it's not interference from other devices. The ONLY commonality is that the trackball sits lower than the dock and below the desktop, as it should. As soon as I put it up on the desktop it works fine. (My chiropractor loves this solution.). Both keyboards sit in the same position and don't have that problem, nor do other Logitech mice I own. It's THIS model.
Great when it works
May 4, 2017
I love the shape and ergonomic. It really helps with the hands when you work in an office all day. However, mine made it about one year then started acting up. I'd temporarily lose connection then have to shut it off and turn it on multiple times to reconnect. It was a real pain in the neck but I thought it was the computer for a while until I got a new computer. This happened more frequently and the batteries had shorter life spans. Then recently it died around 2 years. I may have just had a bad apple. My coworker has one that feels a little better and more refined then the one I had.i may try to get another one since I don't feel like dealing with a wired mouse.
... been a full month now and I am not happy at all
March 27, 2017
It's been a full month now and I am not happy at all. I've used Logitech products for literally years with nary an issue until now. I've done a lot of online research and tried numerous remedies all without success. What's the issue? The scroll speed throttles back to a crawl after switching tabs or performing other tasks. Interestingly I found similar complaints with various mice going back to 2005! This is also my first wireless. My old Logitech wired Marble mouse never exhibited this issue. So regrettably this is being thrown in a drawer as having to constantly reset the scroll function is something I flat am unwilling to put up with. Going back to a gaming mouse. FWIW my best hand device experience was with the fabeled Microsoft Trackball Explorer that served me well for over a decade. Like many others I still wish it were readily available.Addendum: I'm using Win 7 Home Premium - 64 bit SP1

Wonderful mouse... until it stops connecting to the computer.
June 29, 2016
This mouse worked perfectly... for about a month. It now does not recognize that it is plugged in and I have to uplug it and replug it back in multiple times to get it to recognize it being plugged in.PROS:-The mouse clicks are relatively silent-The mouse feels comfortable to hold-Easy to get used to usingCONS:-The wire/usb connection to the computer seems to have failed to be consistent after only a month of useIf the mouse had not started up this problem with connecting, I would be rating it 5 stars. Maybe you will be more lucky than I in your purchase of this otherwise very nice mouse.

I hate using it
August 5, 2017
I bought this mouse to solve the problem I had with my bedroom HTPC and watching TV or surfing the web having to drag a optical mouse over my sheets. Well, I never got used to this ball mouse, I hate using it, and it takes me forever to complete simple tasks, on top of that, it is to big, and has pretty bad ergonomics, you place your hand over it, and have to be guessing which button is the right hand click and which one is the left. I didn't return it cause I was a lil lazy to do the whole repacking, but definitely it is now another unused item filling up my drawers.
It worked fine for a few months
August 2, 2017
It worked fine for a few months, good response, nice weight and feel.The problem I have now is after just a few months the USB connector in my computer just randomly stops detecting it. I have tried the mouse in two different computer in a total of 6 different USB ports. It will work for awhile then randomly just drop the connection. The longer I use the mouse the more and more it just drops out detection and gets harder for me to find a connection. I am going to have to buy a new wireless mouse now and put this one in the trash.Of course i also searched the web for solutions but wasn't able to get anything to work and also tried replacing the batter.
One year later.... trackball isn't cooperating
June 26, 2017
I've had this mouse for just under a year (11.5 months) and it was amazing in the beginning. My wrist stopped hurting. I was able to work longer and be more productive. The trackball took some getting used to, but once I did, I no longer had to even think about it.ONE YEAR LATER: It still looks brand new. No wear and tear, no scratches or fading. However, the trackball has stopped tracking. Okay, well, not exactly. I have to use my thumb and pointer finger to move it. It will track to the right as normal, but to go up, down, or to the left, I have to use 2 fingers. Using just the thumb will move the cursor a fraction of an inch with each full rotation of the trackball. The battery is brand new, so that's not the issue. Settings are fine since it moves to the right just fine. Using 2 fingers slows me way down and is creating pains up my arm after a day at work. So, I'm replacing it.If you're okay with replacing your mouse every year, then buy this one. If you're like me and expect them to last a bit longer, look for something else.
Problems with Connectivity and Problems with Roller Ball
January 23, 2017
I have purchased two of these, one I use on my home computer and the other I use to control my NAS storage connected to my TV. both devices have a very hard time connecting and staying connected. I often have a problem where the mouse / roller ball will not function....the track wheel & mouse buttons still function, but the cursor will not move...this forces me to unplug & replug in the usb dongle, which usually fixes the problem. but this normally happens about once every day, so it's just an extra step and can be frustrating at time as the product is not working as seamlessly as I had hoped. besides that issue it's a very nice mouse!
Amazing Function and Flexibility, Quality Over Time Less Than Stunning
October 1, 2016
UPSIDE: Amazingly easy to get used to, just takes maybe a day to re-adjust your way of thinking from a "normal" mouse and feels very natural in the hand. The main reason that I buy these is that they work unparalleled in small spaces. I use one on my home desk because I often clutter it with work or study materials, and this frees up a surprising amount of space, more than you would think, when overall the mouse itself need not move except to adjust for hand and wrist comfort. It also has the benefit of not being limited by the surface you are on, I can easily sit this on my couch next to me and connect it to my laptop, even the modern high quality laser mouse is not capable of doing this reliably on most surfaces. For that same reason I also use it for the media server and 2nd small computer that I have directly connected to my TV. The function is top quality, the reliability and quality however leave something to be desired, addressed below.DOWNSIDE: I have owned what will be 3 total of these so far. One for work, one for home, one for my girlfriend at home. For some reason these seem to have more problems than any other. I replaced my one at work finally with a traditional mouse as the trackball would act weird however the left click finally stopped working. I am about to order yet another to replace mine at home as the trackball will work fine, then almost stop moving or move erratically. I often have to clean it out and/or spin the ball at high speed to get it to re-register the movement, however this has become a daily thing now. I have probably 5 other different types of mouse from Logitech even up to and including one that is 5 years old and works fine however, those are all laser, not trackball.For some reason these trackball ones seem to show far more wear and tear than the others. I will be purchasing my 4th and final one at least from Logitech and, if that one begins to have the same issues as well I will try another manufacturer.
Relieved hand/wrist pain
August 11, 2014
I was having pain at the base of my palm, just above my wrist, when using the mouse for several hours at work. I've been using the M570 for about 2 weeks and haven't had any pain. Trackball is very smooth and easy to use.(3/21/17 Update) I continue to be able to use this trackball all day without any wrist pain. You must keep the ball very clean or you will get jerky mouse pointer movements. However, popping the ball out to clean it and the rollers in the main unit is very easy.I would continue to give the product 5 stars. Logitech support is another story, this is why I'm lowing my rating to 2 stars.After about 15 months of usage, the trackball would no longer work. The battery led would just flicker red. Changing batteries did not help. Fortunately the M570 carries a 3 year warranty, but the warranty process has been extremely painful and frustrating.3/11 - M570 dies, so I go online and fill out an RMA request. Provided shipping address, PN, SN, proof of purchase and details of troubleshooting steps that I had taken.3/14 - Receive email from Logitech support saying that based on my troubleshooting, they believe the trackball is defective and will send me a replacement, but first they need shipping address, PN, SN, proof of purchase (all of which they already have). I respond within 15 minutes providing all the information (again) they requested.3/15 - Go online and see that no update has been made to my case, so I seen a message requesting an update. Never receive any update.3/16 - Call support to request an update. They say that they require a photo of the SN before they can process a replacement. Not a problem, but why didn't they ask for that originally. I provide a photo of the SN.3/17(AM) - Contact support via live chat to request an update. They've received my photo and will process a request to have a replacement sent, say that a replacement should ship today.3/17(PM) - Call support to request an update. A request for replacement has been submitted, but they are awaiting on approval from a supervisor. I ask if they know when this will happen and am told that they will ask supervisor to approve as soon as possible.3/20 - Call support to request an update. I'm told that my request for replacement is still awaiting a supervisor's approval. After about a 10 minute wait, I'm told that my request for replacement has been approved and I'm told that a replacement should ship in 2-3 days and expect it to arrive in 7-10 business days.So if all goes well, it will only take contacting Logitech support 7 times and 23 days to receive a replacement trackball.

BUYER BEWARD - CHEAP RIPOFF of real Logitech product
November 1, 2017
RIPOFF ALERT! This appears to be a cheap ripoff product - BUYER BEWARE. I've had at least five of the real mice from Logitech (including two wired versions) and this ain't one of 'em. After purchasing this at a great price (red alert), I threw away the packaging, figuring I knew what I was getting and didn't need it anymore.This mouse worked for about 8 days, but was not as smooth as previous versions. The mouse continually lost signal from the receiver, and then finally just died. I went through the entire troubleshooting process on Logitech's support web site. Nothing. That's when I finally realized something was wrong. Duh!Once I took a real look at this mouse, I realized the logo was not a real Logitech logo. Additionally, the receiver was slightly different from one I saved from a previous version. See my attached photos for a comparison; the actual Logitech mouse has a blue background.Now I'm stuck with a dead mouse and no original packaging, and of course, Logitech can't help because it's not their product.I'm finished buying cheap versions and am going for the Logitech MX ERGO trackball next -- the REAL one. My hands and wrists are worth the money.
Poor Micro Switch Design Dooms a Solid Mouse
September 22, 2017
I hate to give it 1 star solely because of the micro switches; but they are a poor design and cannot hold up to daily office work. This is my second M570, an indicator of how I hoped that the micro switch problems with my first M570 were a fluke; sadly, it wasn't. For my first M570, when the switch began to fail, I Googled it and learned of the problem with the micro switches. As compared to flipping the left and right micro switches (soldering involved), I elected to take the switch apart and swap the springs (not a difficult process, but it can be tedious). If you don't mind working with a soldering iron, you can swap the switches or buy replacement switches (part # D2FC-F-7N) from Amazon. At this point, it's just not worth the effort to keep swapping switches. I would probably be a bit more inclined to replace the switches if they were plug switches and I didn't have to solder a replacement switch to the board.Anyways, after a few months, the swapped switch began to fail and I purchased another M570. After about 8 to 9 months, the left micro switch began to fail again. I've swapped the springs again; but, I will not buy another Logitech mouse until the improve upon the switch design.One other item, more of an irritant than anything. The trackball has 3 sensors that track movement; these sensors build up lint rapidly. You will notice that ball movement becomes somewhat sluggish after about 5 to 7 days. So, about once a week, you will have to pop the trackball out and clean the sensors. I use a paper clip to scrape out the lint. Once you do this, good as new.
Do not waste your money
August 30, 2017
Do not waste your money. After only 4 days the forward and back buttons do not respond to commands. The buttons do press in and back but do nothing. After uninstalling drivers and software, reunifying and everything in between, the buttons still did not work. Started reusing my old Logitech mouse and forward and back work perfectly. It is not a Windows problems, it is this mouse. JUNK!
Lousy! Extremely disappointed!
August 21, 2017
Bought this to replace the Logitech Trackball that we had used for the last several years, loved that one, why we bought this one! This one, however, is NOT what we had. Bought in March of 2017 and the tracking, what moves the curser, only works sporadically. Have put several new batteries in, dusted the eye, cleaned the ball, etc., etc., etc... VERY disappointed in this one. Not sure want to try another one!
DON'T BUY - STOPPED WORKING AFTER 90 DAYS
August 20, 2017
Buy the warranty if you plan to buy this!!!!! I cannot stress that enough. The form and function is excellent; I have no issue with it when it works. I purchased this just over 3 months ago and for 3 months it worked great. Then, out of nowhere, it suddenly stopped being recognized by the laptop I use it with, for no reason. I troubleshooted it via the Logitech FAQ, followed hints/tips/tricks listed by other users, but nada, zero recognition. I uninstalled the Unifier software and reinstalled, which worked for about a day, but the next time I powered up my laptop, nada again.It's not a useless $30 paper weight. If it were only $10 or maybe $20 I wouldn't complain, but $30 for just over 90 days of use? Apparently I'm not the only one with this issue either - it's known. I would caution everyone from purchasing this unless you have $100 a year to spend on mice. It's a shame because it's probably the most comfortable trackball mouse I've used to-date, but if it doesn't work, it doesn't work :(
Terrible piece of junk
June 29, 2017
This thing sucks. I've had problems with it from day 1. It takes 10 - 15 minutes to start working after I dock my laptop in the morning. I have to remove the USB drive and reinsert it each morning when I dock. It blows through batteries very quickly. Even when a fresh battery is installed, there is a lag time between my mouse movements and the mouse on my screen. I have never had a wireless mouse that was more problematic than this one and frankly it makes me angry that I didn't return it after trying to use it the first day. At least then I was within my window. Piece of junk.
I should have known better.
November 8, 2015
You pretty much get exactly the quality that you would expect for a mouse of this price. The upright position of the mouse did help my wrist, but overall it feels very cheap. It's extremely lightweight, and since I'm not used to the height of it, I keep knocking it over.My biggest complaint is that this mouse was advertised as a 5-button mouse, but there is no software available to program the 5th button, making it completely useless. I read this in a review after I had purchased it. I should have known better.Unfortunately, I will be purchasing something else and throwing this one away.
