    3.0 out of 5 stars Fantastic mouse - if not for the feet + liftoff issues.
    Reviewed in the United States on October 18, 2017
    This is a fantastic mouse, were it not for a few minor issues, and one glaring one.

    ~Review from a longtime FPS gamer, playing fast-paced arena-style shooters~

    First off, the Pros:
    - A plethora of programmable buttons
    - The ability to program and recall multiple mouse configurations for different applications*
    - Nice shape and weight: I've heard every complaint and a lot of praise about the shape.
    I have 20.3 cm hands (can palm basketball), and I do not feel as though it is too small for me. The mouse I came from was a G400s, and I grew
    to like this shape a lot better. It "forces" you to grip it with something in-between claw and palm grip, it truly is a unique but "good" feel. With the
    grip I use, my thumb is bent into the side of the chassis, which has a nice textured feel to it that you can dig in to, and my ring and pinky finger
    are hanging off the edge of the mouse on the side. The mouse is not all the way in my palm by any means, but the hump is just curved enough
    to provide solid contact with the palm. The whole thing sounds unorthodox, but it allows my thumb and ring finger to oppose each other in near
    perfect opposition, resulting in a very solid grip where I have a lot of control.
    - Fantastic sensor.
    - High quality braided cable for when you do have it plugged in
    - No discernible wireless lag - I've heard claims you can detect it, don't believe them. Truly negligible to non-existent latency in wireless mode.
    - Incredible battery, a 90 minute charge will be good for around 3 days of continuous play IME.
    -The RGB actually notify you of which profile you have active simply by clicking the button on the bottom - very nice.
    -Great scrolling and hyper-scrolling. (not middle clicks)
    -Great tactile feel from clicks on most buttons
    *BE ADVISED: As of the time of this review, nearly a year and a half after the release of this mouse, the Logitech software still to this day is bugged when using the G900. If you try to use the programmable buttons after mapping them to different keys, the buttons fail to respond until you have clicked them continuously several times, then start working again, and this process repeats every time you go a minute or so without clicking them.

    WORKAROUND: Program the profiles and button commands until you're satisfied, then exit the logitech (blue G) software altogether. There will be another slight delay when you click the buttons again, and once it starts working it stops cutting out. You will have to change profiles using the button on the bottom, and the RGB lights in the middle of the mouse will let you know which profile you currently have active.

    Now the mostly minor cons:
    - Construction: It feels somewhat cheap at times, although I think a lot of that has to do with the corners they had to cut to keep the weight down, so
    with that in mind I can't really mark it as a serious drawback. There is however a slight rattle when you shake the mouse in your hand slightly -
    something in there needs to be secured better, not sure whether it's the sensor assembly, the battery, or one of the compartments that holds the
    stuff in place. Needs improvement. Suffice to say, don't drop this mouse.
    - Right mouse button: For a right-hander, it feels more elevated than it should be. This leads to many unintentional clicks of the right mouse button,
    with whatever consequences that might entail for your current task.
    - Clicks: The two side buttons furthest from your palm on either side of the mouse are quite noticeably inferior with clicking action than the nearest
    ones. They feel stiff and you have to use twice as much effort to depress them. Why not make them just like the nearer buttons? The mid mouse
    button clicks are equally stiff and frustrating.
    -Buggy logitech software, as outlined above in the pros. Unacceptable 1 1/2 years after release.
    -Liftoff distance issues. The liftoff distance for this mouse is quite low, which for me ended up being an issue because adding additional mouse skates for more glide (see below) would cause the sensor to stop registering. Being able to adjust the sensor height would be ideal.

    And finally, the big con:

    The feet.

    For such a game-changing product like this one, with the awesome features it has, they managed to get arguably the most critical element wrong. First off, this mouse has VERY unusual feet/skates (refer to the image linked below). The purpose of all mouse feet is to reduce friction/drag on the surface you're using it on. The G900 fails to deliver in this category. I have tried both the generic feet that came with the mouse, and replacement ones from the only company I could find on amazon that had them, called "Hotline Games". All feet that I tried for the g900 wear out faster than any I've ever seen on any mouse I ever owned, by a large margin. After a week or so of daily use on new mouse feet, the problem occurs.

    If you're using a cloth pad, you probably won't notice it all that much, but if you use hard surfaces like me you definitely will eventually, when the glide starts to feel "uneven".

    I wasn't sure exactly what it was, at first. I thought maybe it was the profile button or the on/off switch that was scrubbing the desk, but after covering those two with felt and still feeling the drag I discounted that explanation. So the buttons on the bottom weren't it, but I kept experimenting until I nailed down the culprit: See the V shaped feet in the very center? They go directly below the sensor itself, close to the center of the mouse. For some reason someone thought it would be a good idea to put two wedge-shaped lines opposing each other right in the center of the mouse. Unfortunately not only are the little wedges completely superfluous in attempting to reduce drag, but they cause an outright increase in friction which, due to their notched shape, cause the mouse to "catch" on the surface and gives a rough, scratching feedback.

    So why not simply remove the V-shaped feet, then? That works, for awhile. With a fresh pair of feet, the absence of the wedges makes the mouse glide as smooth as silk. But after a week or so of wear, it starts to cut into the surface again. Then you turn the mouse over to find out why, and you observe a protruding plastic border that serves as an outline for the inner skates. Once your mouse feet get sufficiently worn down, this plastic border starts cutting into the desk/surface and you are back to square one.

    I tried swapping/adding additional feet to the mouse, only to run into problems with the low-liftoff distance that made the sensor stop registering even from raising the height by a couple of mm.

    So sadly, I'm at an impasse with this mouse now after using it for a couple of months. I can either go through 2-4 sets of feet a month (leaving out the detrimental and unusual inner-feet) to remain accurate, or buy something new for competitive FPS and keep the G900 for general use (where it also excels).

    A very regrettable yet critical design defect on an otherwise groundbreaking product.

    5.0 out of 5 stars Equivalent or better tracking than any of my previous gaming mice
    Reviewed in Canada on November 30, 2016
    Okay, this is a $150-200 mouse, so I'm going to write exhaustively about on and off-spec info. I read a ton of reviews before buying this mouse, so I'll try to highlight everything I feel is important. I'm going to compare it to all the mice I've used up to this point, including the MX518, G9X, G502 Proteus, Razer Deathadder, Roccat Kone XTD, and more. Opinions on mice vary dramatically, so if you're interested after reading this, I highly recommend you buy it and try it. If you don't like an aspect of it, simply return it. No harm, no foul.

    The bottom line is... The g900 is amazing. It meets and exceeds every claim I've seen Logitech make. The MS response time is equal to or better than my wired Roccat Kone XTD and G9X, which had the best sensors I'd ever used... until now, that is. It blows my mind that a wireless mouse performs as smoothly or better than its wired counterparts. Over the past month, it has performed seamlessly over every game I've played (Overwatch, Witcher 3, Metro Last Light, Diablo 3, and more). It has completely justified the price, in my opinion. I bought at $152. You can do better if you get it on sale. Shop around.

    If you're MOST interested in the specs, Gamer's Nexus has the best review I've read. They heavily tested the response time and signal quality. Just google Gamer's Nexus G900.

    •• SIZE AND PHYSICAL FEEL ••

    I have small-ish hands, but I've always liked larger mice. However, I've used them for so long, I wanted to try something smaller. The G900 is a perfect medium. It's nicely rounded in the butt, and I make it work effortlessly for palm, claw, or fingertip. It has a smooth plastic finish, similar to the Razor Deathadder, but it feels higher quality. The grip is scored into the plastic. I like this, as it doesn't produce sweat the way a rubber thumb bit can. It's also going to be difficult to wear down. In addition, this mouse is legitimately ambidextrous and fits beautifully in either hand. I used to like ergo mice, but the G900 contours so wonderfully into my hand, I could care less if it was specifically made for L or R handedness. It comes with 2 thumb buttons, but you have the option of putting in 4. I put in all 4, and I appreciate the placement. I never press the right sided buttons by accident.

    •• LIGHTWEIGHT FTW ••

    This might be a deal breaker for some, but 107g for a Wireless mouse is, in my opinion, amazing. Compare that to a Razer Deathadder, which is considered on the lighter side at 105g, and you see that it's right on par. It may not seem like much, but my 122g Roccat feels like an anvil comparatively. The Deathadder (Ergonomic) version comes in at a whopping 148g, so there's that option out there if you are a very large human being. If you want even lighter and smaller, you can go with the Zowie FK2 at 85g-ish, but we're getting real tiny and specific there. All in all, 107g has been a sweet spot for me and is all the sweeter without a wire.

    •• DAT BATTERY LIFE ••

    32 hours is nothing to sneeze at. I've clocked it from full charge to dead. It lasts around 35 hours balanced between heavy gaming and everyday usage. This is without the LED light on. I've read others state around 28-32 hours with full LED usage. The best part is how fast it charges. Sure, you can plug it in and use it as a wired mouse in a pinch thanks to its braided USB cable, but I just plug it into my wall charger for 15 minutes while I eat, and it's ready for a day of gaming. On that note, it charges to full very quickly. 30 minutes to 1 hour will net 100% charge depending on your charger's performance. I don't bother turning it off, as it has an autosleep function at about 10-15 minutes. I'm hypersensitive about keeping it charged, so I haven't come close to it turning off while gaming.

    Whenever you move it to wake it up, it reminds you of its current charge level: green for great, yellowy-orange for another day's gaming, red for "oh god, why didn't you charge me, fool?!" Lastly, it gives you a windows pop-up warning when it hits 30%, which is plenty of warning.

    Update 01/12/2018: There's a new Logitech G900 variant... I believe the G903. It's compatible with a charging mouse-pad. You put it on the pad, it auto charges. The mouse costs SIGNIFICANTLY more than the G900, and the pad itself retails for $100. Don't fall for it. There's no reason you should be paying upwards of $250 for virtually the same product as the G900. Based on my year of experience, the G900 charges so friggen fast, running out of charge is NEVER an issue. Don't pay literally hundreds of dollars more for the same mouse with a gimmicky charging model. It really really really ain't worth it.

    •• SIGNAL QUALITY ••

    Per Logitech's instructions, you should keep the sensor at least 8 feet from a router to avoid signal irritation. I have my dongle about 2 feet from my router and have had zero issues. No mouse acceleration, deceleration, nothing. The movement has been outstanding. One note, though. If you block the dongle with a heavy item like a subwoofer or XBox controller, you will immediately notice sluggishness. It's pretty simple. Don't keep anything directly in front of the dongle, and you're going to have a great time.

    •• CLICK FEEL ••

    I won't harp on this for too long because it's highly subjective, but perhaps the subtlest yet most satisfying thing about the mouse is "click feel." It feels like a tighter, more responsive click than even the Deathadder, which many feel has the best on the market. Like I said of the plastic earlier, it simply feels better constructed (which it bloody well should be for $150).

    •• SCROLL WHEEL ••

    One of the things I find "okay" about this mouse is the wheel. My Roccat's TITAN WHEEL was awesome. It felt thick, responsive, and heavy duty. The G900 goes in the opposite direction in terms of build methodology. They hollowed it out to remove as much weight as possible, which is great... but that makes it slightly flimsier than others. Honestly though, pressing the middle mouse buttons are fine. No issues there. There are two scroll modes: single tick and free scroll. Single tick is good, albeit a little louder than some. I got used to it after a day's use and don't notice it anymore. Some people have complained about the wobble in the free scroll mode. What they mean is that, if you leave it in free scroll while gaming, the wheel noticeably wiggles to the left and the right as you swing the mouse around. There's a simple solution to that problem. Don't game while in free scroll. There's literally no reason to unless you're macro-ing a single shot weapon like a wiener. If you want that, this mouse is way too good for your kind, dude brah.

    •• LIFT DISTANCE ••

    It's low enough that it'll never ruin a shot. I've tested it on my bare wooden desk, my steelseries QCK+, and my Roccat Alumic. There's no awful drag when adjusting. I do recommend you go into the software and tune it specifically for each surface you're using. The software has no limit to the number of surfaces you can save, either, which is nice.

    •• IT LIGHTS UP ••

    Yeah, honestly, I don't give a flart about that. I keep my light off to preserve battery life, but you can use it with whatever color you like.

    •• THE SOFTWARE ••

    Logitech's Gaming Software is decent. I like that it integrates multiple products (headsets, mice, etc). For the G900 specifically, you can change DPI (with as many custom presets as you want), polling rate, LED color, button assignments, and add macros. You can also change the "surface type," but I recommend caution. There are three settings: default, cloth, and hard. I set mine to hard, but I was noticing periods in FPS's where I couldn't even turn. Switching back to default fixed this. You can create your own custom profile, which allows the mouse to theoretically map the surface its on, but that made it feel slightly wonky. Either way, you should experiment!

    Roccat's software, to compare, is slightly more comprehensive. You could change lift distance, horizontal vs vertical sensitivity, and other neat little things. I'm not a fan of too many options. At some point, they're majorly redundant.

    •• CONCLUSION ••

    The g900 is unequivocally the best mouse I've used in 16+ years of semi-competitive gaming. I play high sens (1600dpi in Battlefield, Starcraft, LoL) and low sens (800dpi:7 in Overwatch, COD4, Titanfall). For those with small/mid size hands, palm, claw, or fingertip are all fine, particularly due to the lightweight. This thing crushes in all respects. If you love mice and want to upgrade or are simply looking to cut the cord and start fresh... do it. I don't think I can ever go back to wired.

    Update 08/22/2017: Nearly 1 full year after purchase, I have two updates.

    #1 - The G900 is still amazing. Everything feels like the day I bought it. Zero issues with battery life.

    #2 - There is ONE small annoyance. Once a month or so, even though I've disabled the LED lights, they'll randomly turn on when I wake the mouse. I suspect it's a Logitech Gaming Software issue. All I have to do is go into the software, click into the light area, and suddenly it remembers lights should be off. Takes me 10 seconds or less. This won't affect many people; just be aware!

    Update 01/05/2018: The lighting issue is completely solved. I'm not sure what changed, but something did. However, full disclosure, my unit developed severe right clicking issues. We're not talking double click. We're talking triple/quadruple, and it was so messed up I couldn't even hold it down. This was after about a year and 2 months after purchase.

    I'm hoping it's a lemon. I contacted Logitech Customer service, who were quite helpful. I've sent it back to them via UPS for an RMA. The process was smooth. I'll update when I receive my new or refurbished mouse. The reason I'm not dropping stars is because my Steelseries, Roccat, and Razers have all developed click issues at varying points in their careers. This is the first time I've had a Logitech mess up, so I'm giving them the benefit of the doubt.

    Update 01/12/2018: They approved my Logitech for renewal. 3 days after shipping it from the States, I received it, so they must've sent it hella priority. When the tiny box arrived, I thought for sure it'd be a refurbished model. Nope. They sent me a brand new G900. My faith in Logitech is renewed. The mouse feels just as amazing as the previous. Re-installing drivers was no issue. I've picked up exactly where I left off without a hitch. I will update if there are any future issues. Still, I'm quite happy with the customer service I received.

    Update 05/31/2020:

    Still rocking 2 and a half years later. Zero issues. I love this mouse.
