Side by Side Comparison of: Accessory Power vs Logitech

This is by far the best mouse I've ever used. Granted I don't have much experience going from budget gaming too high end in a matter of months. But I can't find a flawI have fairly large male hands and use a fingertip/palm grip hybrid (my palm doesn't touch the mouse and fingers flat against the mouse) and it fits perfectly, though this hold style fits just about anything.When using palm grip my hand barely encompasses the whole mouse, but middle button is rather uncomfortable if I were to use palm grip, so if you use palm grip with large hands, I'd consider a larger mouse, or same size with a middle button further up.The weight thing is useful, but I kinda just put it at a random weight and adjusted to it.I imagine the dpi shift button is useful, but I don't play FPS often, so I can't tell you it is, but it probably is (especially since dpi shift is adjustable)Preface- there's a button that switches between preset profiles (up to 3 profiles)The profiles are quite useful as I do switch between gaming and school work so having different buttons mappings profiles (reprogrammable by logitech software) plus a G-shift function (holding the button down changes function of each button based on your profile, analogous to using shift for a keyboard) for shortcuts replaces the need for a keyboard for a couple seconds as a copy and paste with mouse alone.The scroll wheel feels firm and definite, but not hard to scroll with.There's also a button the "unlocks" the scroll wheel, to where it's free flowing and practically frictionless. Great for scrolling down long pages and quick zooming out, and fun to play with. Since it loses how definite it is, also reduces sound, so it's nice for that tooEach click feels satisfying, may be too loud, but I'm not familiar with other mice. All I know is that I can't game with my roommate sleeping.TL;DR- bit small for large palms with palm gripTake advantage of logitech software for profilesMany buttonsScroll wheel unlock is useful/fun to play withLooks like a futuristic weaponBest overall gaming mouse

I bought this to replace a Logitech G700 wireless mouse. That mouse worked great but had bad performance when not plugged in, the cord was too rigid because it was made of thick plastic and this made it hard for precision moves.The G502 works fantastically, I have used it everyday for the past 3 months for hours at a time. It is very responsive and has a braided flexible cord that doesn't give met he same problems as my last mouse. I really wish it had 4 side buttons that I could use with my thumb, but all buttons are programmable so I sound a use new use for the DPI change buttons.Because of the way I hold the mouse (more like a claw) I can't reach the "Sniper" button that lowers your DPI for easier headshots, it would have been better if they put it directly under the side buttons. It was probably designed this way so you wouldn't press it by accident.It is significantly lighter than the G700 and comes with magnetic weights that you can use to get the perfect feel. The scroll wheel has a locked and unlocked mode that allows you to have incremental scrolling, good for changing weapons in games, or free scrolling, good for web browsing. This is changed by the button directly under the scroll wheel.

I've bought a couple of these and I've recommended them to dozens of friends and clients (I'm a PC builder) who absolutely love it, and what's not to love? It's light-weight with several 3.6g weight for tuning with dozens of positions to lock them in to get the center of gravity correct, the switches are solid but not too light that I accidentally click them like some other mice I've owned from other big brands, there's not an overload of buttons in any 1 zone, buttons are large and easy to hit every time, the grip is pretty great for palm/hybrid/claw grip and is plenty long to comfortably rest my long fingers. The laser sensor doesn't feel like it has any acceleration and tracks better on sketchy surfaces when I take one to a friend's house than my mice with the infamous Avago 3310. The braided cable is absolutely frictionless on both my glass and wood desks, and the scroll wheel is my absolute favorite of any mouse I've ever used. Some people prefer a rubber grip on the wheel but I've never slipped while scrolling and the rubber on my vx revolution wore out after about 5 years of use, but there's no rubber to wear out here. The side scrolling is sometimes hard to find in good mice these days (I LOVE my Mionix mice but c'mon guys, none on my Corsair M95 either). My only regret is that I just heard they announced the g502 spectrum, but I guess I'll be getting at least 1 of those and giving away one of these now. Keep in mind that it a bit thinner of a grip than many other mice, if you have bigger fingers you may consider something larger like the Mionix Caster/Naos or the Corsiar M95, but I have a couple friends with big hands that still love this mouse more than those with wider grips.

Rivals even the Deathadder in terms of comfort. I use both palm grip and claw grip depending on what I'm doing, and both feel great. I have bigger hands than average, so I was worried the mouse would be too small, but it fits just right. The grips for pinkie/thumb on the sides of the mouse are very comfortable, and the thumb rest is nice too.High quality sensor means zero jitter even at 20,000 DPI. The extra buttons (9 buttons in total) are a nice touch and do not interfere with sensor quality or response time. I love the addable weights and unlockable scroll-wheel, it's something I wish the Deathadder had. The appearance of the mouse is a little goofy, like something kids would love, but who cares I don't stare at my mouse all day.My only complaint is that the mouse wheel click is VERY stiff. It takes the strength of 10 men to push that sucker down, but I got used to it after a couple of months and now I think my finger is strong enough to do a 400-kg dead-lift. Okay not really but it could definitely be less stiff.

This mouse is the best I've ever had. It beats the mx518 in almost every single way, albeit having almost exactly the same shape.The round-ish shape of the mx518 makes it more resistant to shock than the angular protruded shape of the main buttons on this one. But that's about it.I have small male hands and feel confortable with the whole button positioning. Have got nothing to complain about the software, either. For me this is the perfect FPS player mouse!

TL;DR at bottom of review.BACKGROUND:I have been an owner of the Logitech G9 mouse since 2009. I love that mouse so much that I bought a backup G9X when I found out they were no longer being made and panicked that I wouldn't be able to find a similar replacement when my G9 died (it still works great btw). I found this mouse after seeing some people mention it on the Logitech forums when it came out just a week or two ago.I use a hybrid fingertip/clawgrip style which for all intents and purposes can be thought of as just a clawgrip. I have small hands for a man or medium size hands for a woman. The G9 was great for me as it was a small low profile mouse perfect for clawgrip. I used the "precision" grip as it was slightly more narrow and had a more grippy texture.I do the typical everyday typical web browsing and Microsoft Office stuff. In addition to that, I play some FPS games and WoW.G502 COMPARISON TO G9/G9X:(G9 & G9X are the same mice with a better sensor on the G9X for those who don't know)- Size/Form Factor - Slightly more narrow than the G9. Side grip points are rubbery and feels great to grab on to. It is taller than the G9, but not enough to make a difference for my grip style. It is also technically longer than the G9, but most the extra length is due to the longer main 2 left/right mouse buttons. This ends up also making no difference on my clawgrip style because I am still able to click those 2 main mouse buttons closer to the palmrest side of the mouse. Larger hands can click them farther away from the palmrest. I feel like I can grab on to the mouse with my grip style and really have control over it. Overall, I actually like the ergonomics of the G502 better than the G9 (never thought I'd be saying that!)- Weight - I played around with the G502's included weights and ended up liking the weight of the g502 naked. Logitech's website lists G502 at 168g, and the G9 at 153g with precision grip. With the G9, I had 4x4g in the tray for a total weight of 169g. So I ended up liking about the same weight 168 vs. 169g. Ha!...who knew we could discern mouse weights so well? The G502 comes with an additional 5 x 3.6g weights, so the range is 168-186g. G9's range is 153-181g with the precision grip. If you like to use G9 without weights (or less than 4x4g put in), you will find the G502 a little heavier.- Buttons - You get 11 programmable buttons with the G502 vs 9 programmable buttons with the G9. The 2 additional buttons are defaulted to "DPI shift" located at the tip of where your thumb lies, and the "profile switch" button located south of the mouse wheel. 2 standard thumb buttons feel better in that they are "clickier" and located more naturally for my thumb to hit when compared to the G9. The 2 DPI up/down buttons are moved to left of the left mouse button. DPI up ends up farther away north on the mouse which may make it more difficult to get to for clawgrippers.- Mousewheel - Bigger and made of a sort of metal. I prefer the rubbery texture of the G9's mouse wheel better. The metal texture of the G502 almost makes it feel slippery at times, but the groves on the wheel itself, and the reassuring clicking make me feel confident while scrolling. Switch to go free scrolling is now located on the front of the mouse just south of the mousewheel which is much better (and makes it used more) as I don't have to look down and turn over the mouse to switch modes. 3 mousewheel buttons easier to click than the G9. Middle mouse button still stiffer than I'd like but much improved over the G9. This makes the G502's middle mouse button actually usable for me.- Sensor - Obviously mouse sensor technology has gone beyond what 99.99% of people will ever use. G502's sensor is amazing. DPI goes up to 12,000, but I only use 2500. The sensor does feel precise and I don't notice any acceleration. Other people have tested this and note zero acceleration. I use a Steelseries cloth mousepad, and you can tune the g502 to different surfaces with the software...don't know how much of a difference "tuning" really makes in real world application.- Miscellaneous/Software - Uses standard Logitech Gaming Software which works well, and nothing new to learn. Tried to use and tune it on my glass table which didn't work (Logitech does not claim that it will work on glass). Blue G light on palmrest can be turned off if too bright for user as mentioned in another review, but I personally like it and don't find it distracting.FINAL THOUGHTS:Logitech has made, in my eyes, a successor to the G9/G9X...not only that, but the G502 is a WORTHY successor to the G9/G9X. Logitech does not market the G502 as the successor to the G9/G9X, but the form factor, weight tuning, buttons, mousewheel, and sensor all certainly have the feel of the G9/G9X. The thing I wanted most with my G9 were a few extra buttons for gaming. I get 3 extra buttons with the G502 (counting the middle mouse as an extra button as I could never use the G9's because it was so stiff). The form factor of the g502 is great for my small hands, and fingertip/clawgrip style. Again, I think it would be great for larger hands as well due to the longer main left/right mouse buttons accommodating a range of hand sizes, but I'll defer that to other reviewers with larger hands. I am now officially using the G502 as my main mouse, and putting the G9 (and an unused backup G9X) in storage. Sort of sad to put away 2 excellent and working mice like that, but the G502 is an upgrade.I tried to be thorough in my comparison, but I'm sure I forgot to mention things people are interested in hearing about so feel free to ask comment and ask questions.TL;DR - Form factor great for range of hand sizes and claw grip. Shares many design principles (with many improvements, although some not as good ideas) with the old G9/G9X. I am replacing my G9 with the G502 and consider the G502 a worthy successor/upgrade to the G9/G9X.

Has a lot more buttons than I thought it would. Only complaints are the mouse won't wake the computer by just moving it like my MX1000 did and it looks like a toy. The cord is just starting to fray after months of hard use. I might reinforce the cable root at the mouse with a couple wraps of self fusing silicone tape. Also, even with all the weights installed, it still doesn't feel heavy enough for me. I've gotten used to it, but nothing will replace my MX1000. This mouse does a good job of trying.

I think the most immediately relevant thing to most gamers when it comes to this device is its weight. Its pretty heavy, and if you don't like that, or if your hand/wrist gets fatigued easily, you should consider other options. If you like heavy mice, well it even has additional weights that can be installed in the bottom very easily, but the amount of weights, and their total mass is much less than the g500's. All of the buttons are easy to press and are satisfyingly clicky, with except of one of the thumb buttons, which sits too far away to comfortably use without altering my grip, and the button in the middle of the top of the mouse, which I don't think is easily accessed with any reasonable grip at all. Logitech's gaming software allows for a great amount of customization, multiple profiles, as well as the ability to activate certain profiles when a certain application or game is running.One other thing to note is that this mouse was almost impossible to clean when it got covered in "gamer gunk", so if you are susceptible to that, know that it will be incredibly difficult to clean.

Note: Purchased to replace the multiple DeathAdders I've killed inside 4 months with moderate use (only to be sent disgustingly filthy, broken refurbs by Razer's trash-tier warranty "support" center). This review will largely be a comparison between the G502 and the DeathAdder, so if you're an unsatisfied DeathAdder owner and looking into alternatives, or a prospective buyer torn between the two, this review is for you.Drivers: This is a big point of contention for a lot of users. Some despise bloatware driver software running in the background, others don't care. I'm of the former camp, so the good news is that you can run the software, set up to three DPI profiles which are stored on the G502's internal memory and can be swapped on the fly at the press of a button, and then just disable software until you want to edit one of the profiles for zero bloat. You lose all functionality from Razer Synapse when the application is closed, there are no 'on the fly' DPI settings, and Razer is currently cheaping out and no longer making mice with internal memory, so you need to let Synapse phone home if you want to transfer settings among different devices. Logitech is the clear winner here.Ergonomics: It's a complete non-starter if the mouse isn't comfortable, so it's fortunate that it's pretty damned comfortable. I'm a palm gripper, so a long-body mouse is a must, and if the G502 is anything, it's long. That said, there are a couple problems that you may or may not run into. The G502 has an extremely narrow front-end, while the DeathAdder's is quite wide. The result (for me at least) is that with the Deathadder, I can comfortably rest my ring finger on the lip of mouse 2, while my pinky straddles the side; but with the G502 there's no room for my ring finger, so it straddles the side while my pinky just kind of floats there and drags on the mouse pad. You get use to it, but it's still not quite as comfortable as a DeathAdder which is my only real strike against the G502, but it's also the reason it's getting 4 stars instead of 5. Other than that, the buttons are all easy to reach, and the little thumb-shelf on the left is pretty great. It's close, but the DeathAdder edges the G502 out for a slight win in the ergonomics department.Build Quality: I've been using it for a month, which isn't enough time to gauge long-term build quality. Every DeathAdder I've owned has begun double-clicking between within 2-4 months, along with the scroll wheel loosening up to the point that the tactile clicks become nearly imperceptible, and the last two (one 2013, one Chroma) have also had the middle-mouse button-press stop registering unless pressed with extreme force. I've also had the cheap adhesive holding the rubber side-panels on peel off after a week on one of my 2013s. I baby the hell out of my peripherals, wiping them down weekly with a gentle 75% water, 25% isopropyl alcohol mix. I never slam them, hammer on the buttons, or spill things on them; yet the Razers constantly fail prematurely (and you won't have to look hard to find several thousand reviews describing identical failures). The G502 feels well-built; Mouse 1 and 2 are solid, separate buttons (unlike the DeathAdder's which are part of the chassis that bends), the scroll wheel is steel and the clicks are very tactile and 'chunky'. The mouse itself is feels sturdy and is surprisingly heavy, even without the weights installed, and the rubber side-pads are extremely secure with no signs of loosening/peeling. All is roses, except for Mouse 7 and 8 which feel flimsy, similar to how a DeathAdder's Mouse 4 and 5 feel.As it stands, I'm tentatively happy with the purchase, and will be even happier if it ends up lasting at least a year or two before failing. If/When it fails, I'll update this review accordingly.**Update**As of 5/7/16, nearly 7 months of heavy use and the 502 is still kicking, no double clicks or breakage of any kind. The scroll wheel has loosened up as expected, but besides that the mouse is still 100%. It has officially outlasted every DeathAdder I've owned by a minimum of 3 months.

Functionally, I really like this mouse. I don't use the weights or any of that gimmicky stuff. I was using the original Sidewinder and had gotten really used to the vertically spaced buttons. This made a great alternative to that without the fuss of the sidewinder. DPI settings switching is interesting but seldom useful to me. Button placement creates some confusion with main mouse button during gaming. Sniper button? Tried it a few times then reassigned that button to a thumb button to get my vertical button placement. Works great. I personally don't need a "sniper" button. The functionality of it works fine, though.Grippy on the sides, smooth on top, glides well. Polling rate adjustments in conjunction with DPI adjustments make for some sensitivity adjustments. Settings can be saved to the mouse. I don't really move the mouse to another computer, but it sounds nicer than having to connect to internet to use your mouse the same way. Overall size is on the small side. I wear large size gloves, so my hand is pretty average in overall size, and I find the mouse small for my usual grip style. Had to adjust to more use of my fingers to move the mouse rather than resting my hand on the mouse body, though it does still sit partway on there some of the time. The sloping back of the mouse isn't really a great place to lay a palm on. Previous mouse had a large hump area to rest my hand on, which I found comfortable. This does not. It took some adjustment, but it's fine now, but felt awkward for a long time. The wing on the left side I wasn't so sure about, but find it very nice to rest my thumb on. I find I use less tension on that side to hold the mouse since that is there. The mouse is proportionately narrow so I end up having to grip there more. While it does have a grippy surface, I have to hook my fingers quite far to contact that surface. Taking a longer grip (I believe it is often referred to as a claw grip) with mostly fingers holding the mouse seems to alleviate most of my issues.If they ever make a bigger version of this mouse, that would be nearly perfect. Size is probably the only issue with this mouse for me as everything else has worked just fine or even great.I like the mouse, though I

After my Razer Death Adder's left button wore out I chose this as a replacement based on the numerous reviews across the web.I received it today and have been playing around with it for a few hours now. Here are my initial impressions.Visual: This mouse looks really good except for the gray triangle where the DPI lights are. That should have just been black like the rest of the mouse or at least the shade of blue used on the thumb rest. The overall design reminds me a bit of the Delta Flyer from Star Trek Voyager which I think is pretty cool.9/10Ergonomics: My hands are larger than average and based on the reviews of others I was concerned about this until I actually put my hand on it. It is definitely the best feeling mouse I've ever had. All the buttons are easily accessible from both a palm and claw grip and I can much more easily switch between the two than I could with my Death Adder.10/10Buttons: The placement of the scroll type toggle sucks. I will never use the free scroll wheel so I would greatly prefer for an assignable button to be placed here instead. The three side buttons are placed well and are easy to press on purpose but not accidentally. Although I did have some issues accidentally hitting the dpi shift at first a few times its not longer an issue. The DPI up and down (or lefter clicks as I like to call them) were almost maddening at first but like the DPI shift I got used to them being there and no longer hit them accidentally. All of the buttons have a great tactile feel.8/10Scroll Wheel: The scroll wheel is my least favorite part of this mouse and has numerous problems. The feel of scrolling is far inferior to any other mouse I have had although it works fine. The wheel itself is slick and if your finger has too much or not enough sweat on it it will slide off of it while trying to scroll. The free scrolling mode is a joke. I dont know why anyone would ever use it. The tactile feel of pressing down the wheel sucks and is more difficult than it should be, however the scroll wheel makes up for this with the left and right tilting action which feel great and are easy to use.5/10Tracking: Amazing. I did a side by side comparison with my death adder and the G502 clearly out performs it on various DPI settings on my Steel Series mouse pad. This is why I chose this mouse and I was not disappointed.10/10The Weights: Silliest thing ever. Obviously just a gimmick. The weight and balance of the mouse is fine without them and I dont notice any difference at all with different weight configurations. Well except having them all in. Then the mouse is too heavy to slide smoothly.0/0Software: Pretty standard gaming mouse software... Pretty much identical to every other mouse I've had except the profiles are stored on the mouse itself which is great.10/10Conclusion: A great looking mouse that provides excellent performance albeit with an unfortunately sub-par scroll wheel and some useless features. Now comes the durability test. Will it last longer than my 2 year old Death Adder? If not will Logitech honor my RMA in a timely manner? Will the feet wear off like so many others have claimed in their reviews? Only time will tell.Initial Impression Rating: 8/10Additional Thoughts: A pinky rest on the other side would be nice.

Best mouse I have ever used. It's ergonomic design and look is very nice. I have a skinny small hand. But my fingers reach every button without any problem. The weight? Good enough for me. I don't like heavy mouse. Light mouse either. The only downside I noticed is the scroll wheel. It seems like it's jamming. When you wheel up or wheel down you will have to use a lil lil bit force. When you use lil bit force, u're gonna feel like you are going to click the MB3. That's the only thing I feel uncomfortable with this mouse. Especially when you wheel up you will need to put a little bit pressure on the wheel and then you can roll it. I hope U get what I mean.

I honestly do love this mouse. It works perfectly and looks awsome and the customization for the buttons is very useful. I do not like how it fits the hand, however. This is extremely important for gaming with precision in FPS. Your pinky drags along the desk/mouse pad no matter how you hold it. It's very comfortable for your thumb and index finger and middle finger area but it's a slender mouse and does not provide a groove for your ring finger or anywhere for your pinky. It curves inwards on the other side like an ambidextrous mouse and does not provide the grip that cheaper mouses come with. Even if you place your ring finger on the right click button right next to your middle finger, it feels awkward and your pinky still drags across the mouse bad. I've had the mouse for a few days but I will update when/if I get used to it, but so far the grip has hindered me a lot in FPS games like Overwatch. The click buttons feel slightly loose and cheap as well. But overall, aside from the feel, it's a fabulous mouse.UPDATE: Apparently I use a "claw" grip on the mouse in case that makes a difference.

I like this mouse and will start with the positive: it's very flexible. The software lets you rebind everything and you can switch through 3 profiles directly on the mouse. The lower thumb button by default is set to a DPI shift for "sniping", or G-shift which can change how each button acts. This is great for productivityMy complaints are with the button placements. I have average sized male hands, and some of the buttons are awkward or impossible to click. The lower dpi button is awkward to press and the second thumb button is practically impossible while using the third thumb button. The scroll wheel is nice, but the left and right middle clicks are too weak. It's way too easy to accidentally press one while middle clicking - which fells good. Normally I'd bind left and right to next/prev browser tab, but I had to set them to the G-shift to avoid pressing on accident. The only use I've found for the extra mousewheel clicks are as a hair-trigger middle mouse button

There is a lot to like about this mouse. The braided cable is fantastic. The mouse has a good hand feel, good ergonomics. It has a lot of buttons but all of the buttons are well placed and easy to hit. The free-scrolling toggle is a neat feature, even if it's not one that I would use. The mouse supports weighting in a variety of different configurations, balance, and weight, sure to fit just about anyone's preference. I don't like blue lights on my devices, mainly due to the disruption blue lights have on sleep cycles, but you can turn the LED off in the Logitech software so that wasn't an issue (after doing a firmware update through the software). I've recently tried using the G300s, the G402 and the G502, after coming from an MX518. Unfortunately, like the G300s, the main problem with this mouse is the scroll wheel. The scroll wheel is made of (I think) aluminum which definitely gives it a premium feel. The mouse notches extremely well, giving nice distinct feel going from one notch to the next, making it clear each time the mouse wheel has advanced a notch. In this regard, it is light years ahead of the G300s which was mushy and indistinct, and still better than the G402 which has an acceptable feel but could be improved. One small complaint is that I have very dry hands and often my finger would slip on the wheel instead of gripping due to the smoothness of the metal. Most people, with normal-moisture-level hands will never have this issue and it was easily overcome by adjusting the pressure on the mouse wheel. However, I've never had this issue ever before with a mouse with plastic or rubberized wheels so it bears mentioning. The major complain with the mouse wheel is that clicking the wheel would cause the mouse to also click the left-scroll button (which is only supposed to activate when you push the mouse wheel left). This would happen about 50% of the time when I tried to click the mouse wheel. I found out that if you middle click at the base of the wheel, it would never happen but that would require you moving your middle finger back into an awkward position and really became rather annoying. Almost any time I would try to click the wheel using a normal finger position, it would also click the left scroll. An easy fix is to remove the actions from the scroll-left and scroll-right buttons in the Logitech software but really this should not even be a thing you should need to consider doing. It also worried me because the scrolling actions add complexity to the mouse wheel, a wheel already made complex by the free-scrolling toggle mechanism and my thinking on this is that if it's already screwing up when it's brand new, that doesn't give me confidence that the wheel would hold up year after year. At this price point, there is no excuse for this happening. This is one of the top-of-the-line Logitech mice and in my opinion, should be rock solid. For some reason I can't explain, it actually started annoying me every time I could feel the mouse doing the scroll-left click when I clicked the mouse wheel. It got more and more annoying as the days wore on. I know this probably shouldn't have bothered me so much but for some reason, it really did. I finally decided to try replacing it with the G402. Unfortunately, the G402 doesn't have near as good of mouse notching. It didn't feel quite as mushy as the G300s but neither do you get a good distinct click when moving from one mouse wheel position to the next. The G402's mouse wheel barely gave an indication when going from one notch to the next and if you only touched the mouse wheel lightly, you didn't get any click at all, just a rubbing feeling from inside the wheel. Despite that, I ended up sticking with the G402 because I couldn't stand the G502's quirks anymore.Update: One year and a half later. The G402's mouse wheel failed completely. I decided to jump ship and bought a Corsair Saber (which has an excellent mouse wheel btw) and never looked back. I'm done with Logitech mice.

I liked the mouse. It was comfortable, the left- and right-click buttons are well positioned and click with a desirable amount of pressure. The side rubbers allow for a good grip. The resting position of the scroll wheel wasn't causing accidental scrolling like I've had on previous mice, but does take more pressure to click than I'm used to. The infinite scroll was interesting, but I didn't find it that useful. I really like the look and the stock weight avoided it feeling cheap or flimsy.However, I ended up returning it. I utilize a full-on palm grip. I was looking to get a mouse for my backup computer and I figured I could use my Logitech G5 on that and upgrade my computer's mouse. The G5 is perfect for large hand and grip style.The first thing I noticed when I tried the G502 is that, when using palm grip, the thumb button is right there under my thumb. It prevents me from slightly squeezing the mouse to get a good grip. It mis-clicks every time I reposition my hand on the mouse. Unbinding it prevents accidental actions, but it's still there preventing me from getting the grip I want. Utilizing a semi-palm grip with my thumb just before the button was okay, but it just made me wish I was using my G5.If you use a claw grip, a partial palm-grip, or have medium or smaller hands, I strongly recommend at least checking it out. I've just become to accustomed to my G5's shape that anything else feels foreign.

Does this have all the technology you want from a mouse yes. Is this a good mouse overall, I would say yes.I bought this mouse along side my G710+ keyboard. Love the keyboard, not a fan of the mouse. I have been using it since December 2014 for general computer use, and playing BF4.Coming from the size of the G700, and prior G9, I hate the size of this mouse. I have a large glove sized hand, and this mouse feels really small in my hand.I am what is called a masher when playing FPS, so I push hard on my mice, and this one does respond, but not comfortably.I took a break for a few weeks thinking it was my style, but soon after playing a couple hours of BF4, my hand was soar, due to the grip.For most, this is probably great. I wish they would release the G7xx form factor, but with all the tech this has build into it.

I'm going to deviate from all the rave reviews here and say that I don't like this mouse. I also own a G500 and G9x, so I have some basis for comparison. The performance of this mouse is fine, but in the ergonomics department it falls short in the following ways:a) The thumb button is positioned terribly. I don't like the feeling of having to curl my thumb in to avoid rubbing on the edge of the button.b) The 2 buttons next to the left click are way too lightweight. Just rolling your finger lightly on them will trigger them.c) The mouse shape is far narrower and lower profile than the G500. This mouse is pretty much a claw-gripper, which is something I don't like doing and didn't have to do with the G500 or the G9X. If you think "oh this is a G500 replacement and it will feel the same" ... think again, it's a totally different feel.d) The triangle-cut texturing they applied to this mouse feels rough and awkward to grab onto.In my opinion, they were trying too hard to make a mouse that looks cool and all transformer-ish with angles and edges everywhere. Judging by the reviews here, clearly a lot of people like this mouse, but if you're a palm gripper like me with long fingers, you're probably not going to like this mouse. I went back to my G9x after a couple weeks and it feels much better.

Been using G500 for years and very comfortable with it. Thought this item would be a good replacement with newer features, however, when I got it it felt clunky and awkward to use. The dealbreaker for me was the mouse wheel, which would either spin freely or, when in click mode, was difficult to turn with one finger without applying a lot of pressure. Overall, not happy with it at all and it's going back.

I am at a total loss at trying to figure out what is going on with this mouse.None of the buttons on the mouse will work after the computer has been started. It will track just fine, no problem there, but no button will function. I have to use my old mouse to "jump start" the G502 by opening the LGS software. Only then will the G502 buttons function.This was the case from the moment the mouse was first plugged into the PC. Upgrading LGS and firmware has not made a difference. Tried the mouse in BIOS, it works perfectly. Tried the mouse without the LGS software, it works perfectly. As soon as the software is loaded (which requires a reboot), the buttons cease to function until "jump started".Once jump started, the mouse works perfectly. Seeing that there is more than 2000+ positive reviews, it would seem that it's something on my end, but I am at a total loss to figure out what it is. So this is getting returned, which is a pity because it's a good mouse and I really like it.

Going from my ~8 year old MX518 which started to experience disconnects. Sad day. Ordered the G502 and had high hopes for it since it didn't have too many buttons, had a cool wheel, and had great reviews with people comparing it to the MX518. I got it and was left a little miffed. It is NOT a good replacement (shape-wise) for the MX518. The right side of the mouse completely drops off with nowhere for your ring and pinkly finger to rest. Sure, it has a nice material there, but it actually completely curves back into the mouse. I have 8.5" thumb to pinky hands and I use a fingertip grip (palm does not touch the mouse). I thought I would naturally go from the MX518 to this, but not really. I don't use any of the weights in it, but it is a very cool option and works well.Pros:-Nice build materials and cord (wrapped, but is a bit stiff)-Super customization-Metal wheel has free spin and is cool metal-Extremely smooth tracking (wow!!!)-Sniper button is sweetCons:-NOT the same shape as the MX518 for fingertip users-Right side of mouse is non-existent-Wheel has a heavier click to get used to.-Left edge of mouse (just under the blue part) is sharp and is rough against mousepads if you pick up your mouse and drag it on the edge.-Might be too easy to hit the DPI switch buttons next to the left click.

As a high ranked CSGO and League of Legends player, I was more concerned with form over function. Aesthetically, the mouse looks great, with a matte finish and an ergonomic design, however one MAJOR point to be wary of is the size of your hand and the grip that you use.If you are less conservative and are willing to change your grip from palm to claw, then by all means, this mouse is most definitely worth your money; however, players that use palm grips will find the button layout awkward and annoying (my thumb is the perfect length to be resting on top of the G-SHIFT button, and the raised button makes it feel like a large block of plastic is preventing my thumb from resting on the left side of the mouse)After reading the reviews, which had warned of the same issues, I was optimistic as I have naturally small hands for an individual. Hoping that this would compensate for the mouse's unfriendly palm-hold shape, I bought the mouse anyway. Unfortunately, my small hands still felt awkward on the mouse, and this prevented a firm grip; as much as I hoped this mouse would fill the spot of a much-needed upgrade, I am returning this the first chance that I get.

Coming from the G700 gaming mouse, this thing was a massive downgrade. More than I would have ever expected.It flat out doesn't work on many surfaces. The scroll wheel takes more effort than it should to spin (in notched mode). The two primary mouse buttons are very loud and feel no different than the $5 logitech mice.The underside has so many angles that this thing loves to rub against my cloth mouse pad.And the worst part is, the mouse speed is just ever so slightly inconsistent. It doesn't matter what surface I use, or if I use a USB 3.0 slot. Sometimes there is a small spike where the cursor goes slower, clunkier, or jerkier than normal. I never expected this from a wired mouse.Spend the money and get the G700. Problem with that one, after about 3 years it randomly dies (even when charging or with full batteries), restarts, and for a few seconds you are stuck with the native mouse sensitivity until the driver says "Oh yeah, you want 2500 DPI, here you go".Logitech really needs to figure out their software. Gaming mice CANNOT have these sort of issues. They need to be completely stable.

I've been an avid Logitech mouse user for 10+ years. This is the first time I will be returning a Logitech mouse and buying a different brand.First of all, I believe the seller (High End Tech) sent me a used mouse. The mouse was not professionally packaged, and it was missing the manual. The cable was slightly frayed, the feet were scratched, and the mouse was slightly dirty.If this was the only issue, I'd just repurchase the mouse elsewhere. However, the primary issue is the mouse feet. I have a slightly textured mousepad, but all of my other mice glide over it. The G502 felt like I was pulling sandpaper across it. I believe this is because some of the feet were inverted slightly, making the point of contact to the pad very small. Most of the drag seemed to happen with the pad right under the thumb rest.On a positive note, this mouse did have a nice form factor. It's similar to the MX518 and G5, but with extra buttons that were very well placed. I'm sure this mouse has a great sensor as well. Unfortunately, none of that matters when the mouse struggles to slide across a mousepad.

Very disappointed with this mouse. The software needed to control it crashes my freshly installed Windows 10 computer. Looking around the web I find that others are having the same issue. And before you try Logitech, I'm not interested in troubleshooting the issue. There is no excuse for such poor quality control. On a brand new install of Windows, there should be NO issues to troubleshoot. This should have been correct before it went out the door. I will not buy any Logitech product again after this. I'm very disappointed with this product and Logitech.

The most uncomfortable mouse I have ever used. I got it just based on the rave reviews but I really do regret buying this thing. To start, I have larger hands and use a claw grip and if you do too, save your money. I tried it for a few days and I would be cramped up in a half hour.Down the listRMB seems much more sensitive than LMB. I find myself accidentally right clicking SO MUCH, Just while browsing. Never been an issue with any mouse I have ever used.The scroll wheel is SO STUPID. Unlock it, the mouse becomes unusable. Just moving the mouse around normally will cause the wheel to spin forcing you to scroll. When it is locked its loud and doesn't even feel good.You cant even change the color of the stupid light.Logitech really lost me with this one. Would not recommend to a friend. Or anyone with bigger hands.

Comfortable mouse for large hands. Tracking was nice. Mine was broken on arrival.Left Mouse button was sticking when pressed and made a weird noise when released. So, I returned it.I would have had no problems with this guy otherwise.

I'm giving this one star because the drivers for this mouse are the Logitech Gaming Software, and it's honestly the worst software/drivers I've ever had to use for a device. That software completely ruins the quality of their G35/G930 headphones, and not surprisingly, it doesn't work well for the mouse.In particular, I can't get games to recognize/use the thumb buttons on this mouse. Only one of them works in games and the other two do not. They do work in Chrome as far as Forward/Back functionality, so I know the buttons work, but games don't recognize them.This is the last Logitech product I'm buying until they greatly improve Logitech Gaming Software or stop using it.

Mouse tracking broke after less than a week of use. All other buttons still function on the mouse, and it was great while it "lasted". Reinstalled drivers and everything, after the last few attempts at a fix the tracking light went out and has remained out. Doesn't work on any other computer in the house either. My favorite feature was how it failed during the middle of a gaming session, while using a macro, and I had to restart my whole system as the macro kept going regardless of the mouse no longer being plugged in. Highly disappointed as, like I said, the mouse was great when it worked.

I've had this mouse for about 3 1/2 months and the right mouse button doesn't work anymore. I'm a heavy gamer but i take good care of my things especially my computer and its hardware. I loved the feel of this mouse and it worked great had great customization but sadly it broke very early on. It broke while i was playing WoW (Which isn't very often), just all of a sudden the right mouse button doesn't work. I've tried unplugging it and putting it back in, tried different usb ports, even tried turning my whole PC on the back off. It's sad that im left with this none working $80 mouse after just 3 short months.
