Nice soft touch coating and quiet scroll wheel operation

Great simple product, I just bought my third one. They just work, feel nice, have a scroll wheel with a light action, and doesn't sound too loud. I'm not in love with having "Amazon basics" written on the top, but at this price I'll take it.

Pros: Comfortable for either hand, Side-scrolling, Wheel actually clicks, Fairly nice visual appeal

Cons: Software installs unnecessary components even if one selects drivers for "Mouse Only"

This is actually a very good mouse for the price. Although it's not the cheapest mouse available, it is a solid-feeling mouse with very good comfort. The mouse is only 3 buttons, but please note that the side scroll (used by moving the wheel to the left or right) may be assigned macros or tasks (e.g. double click).

There are less expensive, yet still sturdy Microsoft models, but many of these I have a problem with the "smooth scroll" of the wheel. The clicks give a familiar feel, while the wheel is neither too firm, nor is it too loose. The amount of pressure required for left or right-clicks is perfect as well, with only a slightly more than modest noise level. I myself have fairly large hands, and it fits very comfortably, yet I can safely say this will be appropriate for an individual with smaller hands with similar or equal comfort.

The software is fairly easy to use, with everything clearly explained in the help file. The file is a surprise for me, as I'm used to simple indexes that are difficult to use or simply not very effective. Every option is explained, and a decent amount of customization may be performed. Also for the gamer, there is the option to exclude any or all settings from the mouse in-game as well as merely on the desktop. My only complaints are in the mouse's software, so please heed a caveat: the mouse's software bundles (Musicmatch?) Jukebox, so make sure to pay attention to the installation process and uncheck this component as you most likely will not want it. Also, the software still includes unneeded receiver and keyboard components, which may be safely removed by going to the program files and deleting the respected folders.

Overall, I'm very satisfied with my purchase, and I have used all sorts of different mice in the past, yet this simple and comfortable mouse pulls off a pleasurable experience in its usage. For those of you that like a wired mouse, and want a sturdy mouse without forking over $50+, this is for you. Whether you use PS/2 or the USB, this mouse seems to have no problems with power-saving modes, and is very responsive. I highly recommend this mouse, and I hope others may have the same pleasureable experience that I have had.

I purchased this trackman wheel because at the office I have a limited amount of space for my mouse and I got tired of trying to click and drag over and over because I couldn't get everything highlighted to select.  This trackman wheel gets the job done in one swipe of the mouse.  Still getting use to having the cursor exactly where I want it, but I believe a little more use and that won't be a problem either. I also like the fact the it has a scroll wheel.

Beautiful and smooth to touch. Holds small scroll only and there is a sealable back cover to keep water out once mounted.

I love this mouse. It's very comfortable to hold and very precise. Takes no time for me to get used to it. The scrolling wheel is very smoooth. I understand the complaint of hte wheel click as a middle button, but I never used it, so it doesn't bother me. the Most often used buttons other than the main 2, are the forward and backward buttons. They are not as big as the original MS optical mouse side buttons, but they are less likely to be clicked accidentally. So far I love this mouse and have no complaints.

First off, I must say this mouse pad is NOT compatible with ALL optical or laser mice. For example, the Roccat Kone Military barely tracks on it, whereas the Logitech g502 has no problems (doesn't need to have surface calibrated).

The product is basically a glass pane that appears frosted and has an opaque color on the underside, allowing mice to track. Out of the box, it is a pleasure to use, however the glide is not quite friction-less. When gliding a mouse over the surface, there is an audible sound of the feet running over the glass. With headphones on, I can barely hear it and the sound is far from shiver-inducing. The edges are rounded out somewhat to save your wrists from lying on hard, sharp edges. The size of the mouse pad is about 20% bigger than your standard cloth mouse pad.

Couple things to keep in mind when dealing with the I-2:
1) The more dust on the mouse pad, the less smooth of a glide you're going to get. I recommend cleaning with Windex every so often.

2) Try not to introduce anything like sand or dirt to the bottom of the pad, because it is easy to scratch off the bottom painted layer.

3) The glass acts like a heatsink. You'll notice that it pulls heat from your wrist.

4) Because this is a glass pad, your mouse feet will wear down. When two objects rub against each other, the softer object will wear down faster.

5) Apply silicone lubricant (i.e. WD-40 Specialist) to mouse feet combined with a freshly Windex'ed surface for optimal glide. This gives you an ice-rink type of glide that is incomparable. It glides even better than a freshly Pledge'd Ratpadz XT (hard plastic mouse pad). The glide is so good that it made me like the g502 even more, making the mouse feel much lighter.

Final thoughts: Coming from a cloth pad and a Ratpadz XT, the I-2 just blows them out of the water. With the I-2, I don't have to worry about it warping like I did on the Ratpadz XT. It is fairly large, and adequate for most low sensitivity players (I usually run 400dpi and 2.0 sensitivity in CS:GO for example). Again, the glide is like no other, especially after cleaning the I-2 and lubing your mouse feet. As the name of the product suggests, it's an experience that is second to none. Even if the pad is pink.

I have owned this mouse for about 6 months now.  I like the buttons and it fits my hands real well.  However, like some people I don't like the low resistance of the scroll wheel.  Sometimes I find myself scrolling when unintended.  Also, the wheel click is hit or miss.  Sometimes I have to click 3 or 4 times to get it to go through.  This is with the microsoft drivers and I have tested it on multiple computers, so its not a computer thing.  Other than that I really like the mouse, it works on virtually any surface and the placement of the side buttons really work well for me.  Also with the software, the buttons can be programmed to be application specific or global functions.

This product is great!  It has a nice weight to it so it does not feel to light.  I like the different buttons. and that the scroll wheel can also do horizontal, and the scroll button can easily be changed to scroll quickly or precise.

Outstanding product for a good price. The scroll wheel is innovative. Once in a while I hit the scroll wheel unintentionally; it's not the most ideal gaming mouse, but still decent for first person shooters. Great budget buy.

Another great mouse from Logitech.

I previously used a G500s. The improvements over this mouse include: Use of a rubberized grip rather than a rough textured plastic, which wore away very quickly; a smaller grip that's great for palm, claw, and hybrid grips; a textured metal scroll wheel that is easier to clean (as opposed to the old rubber-metal hybrid scroll wheel, which I personally prefer); a cable strengthener at the mouse front; raised button labels rather than etched/printed ones that might wear away; more lighting options in the software (no RGB though); surface calibration options in the included software; an extra button below the scroll wheel; a different weight system; and perhaps most importantly, a "Perfect Sensor" with no known hardware acceleration.

Changes I don't like: Scroll steps are heavier on this mouse with free scroll off, but many people have complained about the scroll steps on the g500s being too light. The sniper thumb button is a bit hard to reach for palm grips, and the mouse is just a smidge too small for a "perfect" palm grip for me. The scroll wheel is a lot noisier in free-scroll mode due to wiggle room in the scroll wheel assembly. The left mouse click button is recessed instead of raised and following the curve of the mouse, this is mostly personal preference. My biggest gripe though is that the free-scroll switch doesn't activate very soon, which makes it feel rather unresponsive. I worry that it will get mushier over time and I much prefer the feel of the smooth scroll switch on the g500s.

Missing features: While I'm not a part of the RGB lighting craze, I do understand why some people want to color-coordinate their peripherals. It's kind of disappointing that Logitech hasn't added such a simple thing to this mouse. There are also no mouse lift-off height settings in the software, for a "tunable" mouse this is really a missing feature. It might be possible for Logitech to implement this via a firmware and software update. Keep your fingers crossed!

Why buy this mouse? Most of the above criticisms are nitpicks, though mouse lift-off customizability needs to be implemented as this mouse is being marketed as a "tunable mouse." This is a great mouse that should last a long time if you take care of it. The ergonomics are great, the software is absolutely great for both beginners and power-users, there are plenty of well-placed buttons, and the features are plentiful. Buy this mouse. https://www.reddit.com/r/g502masterrace

Side note: I've noticed that they've kept the "sweat-proof" coating from the g500s, yet it isn't mentioned anywhere in Logitech's marketing. I have no idea if it's voodoo magic, but the hydrophobic coating actually works and feels much better than a glossy surface. It is only applied to the palm area and shouldn't wear away under normal use. Don't wipe the mouse with soap!

Good hand feel for medium sized hands but a little too long.  Also, I know it's a selling point to have a frictionless scroll wheel but I personally like a little tactile feedback with my scrolling.  No feedback is a little disconcerting.

I bought this to use with my Macbook Pro (2010). It is a great little mouse and works fine except for the scroll wheel. I have not used it on a Windows computer so the wheel may work fine there. But for my Mac the wheel only scrolls intermittently and then jumps down several pages or only a few lines. So I use the track pad to scroll and the mouse for everything else.
As far as the design goes it fits very comfortably in my hands, which are smaller than average (between a small and medium pair of gloves). It is weighted nicely. Not heavy but enough there that you know you are using it. The overall construction feels solid and I have never been gentle with it when putting in my bag when on the go. The white coloring is starting to get dingy but that is to be expected.
Overall I have been pleased with the mouse and would recommend it to anyone looking for a decent affordable bluetooth alternative to an Apple Mouse.

I use this on Linux using the ckb-next application for customization. Love it! Very tactile clicks, and comfortable to hold. The scroll wheel feels solid unlike my previous mouse. The only thing I dislike is that it is a smidge small for my large hands and doesn't quite fill my palm.

This product has been working very well. One of the things i'd rant and rave about regarding this mouse is the SILENT CLICK. It's got just a few millimeters of travel and a super quiet and soft click, so it actually feels really comfortable. It's shape is very low profile which will take some getting used to. I've been using it on a wooden desk w/ no mouse pad and it's been responding well. The DPI settings are a little too far apart for my liking. If there were some settings in between the 3 that were present, I think i'd be able to find a happy medium, but for now I just left it on the lowest DPI setting. The battery life has been great so far. Micro USB means any phone charger (non apple) will work to charge it up and the bluetooth response is VERY quick even when the computer is in sleep mode. I've been using it w/ my Macbook Air and it's had only one lag issue which was resolved by restarting the computer. Overall, i'd recommend this product if your'e tired of potentially losing the dongle for those USB controlled mice. Bluetooth is the way to go and at this price, you can definitely experience it.

Update 3/14/15: Reading the increasing number of 1-star reviews mentioning touchscreen and screen troubles and outages from ribbon failure or other causes (known and unknown) I feel very lucky now because mine continues to work so well. The included instructions urged slow, careful sliding on the hinge, I recall, and I will continue to change screen positions very slowly and gently, since this design apparently leaves vulnerabilities--or maybe Toshiba's quality-control is spotty as other suggest--or both. But I'm still very happy with mine and it has functioned reliably and adequately, so far. This doesn't feel heavy to me at 3.2 pounds and the relatively short up-to-4-hours battery life (which I knew about before I purchased, so I didn't subtract stars) serves me okay because I'm rarely far from an outlet, but ultraportables are getting lighter and lasting longer and when I buy another I will seek longer battery life and lighter weight.  Those thin buttons on the side are easy for me to feel and operate without having to look and I've gotten used to the smaller, stiffer touchpad too (didn't even try to adjust the settings, just kept working, growing accustomed, but I understand it could frustrate).

Original review: Yes, the Touchpad is stiff and the On/Off, Volume and Screen-rotation buttons (on the left side toward the back, as I face the laptop) are tiny, as a reviewer somewhere noted, but these minor inconveniences haven't slowed me down yet. So, I'm unlikely to push any of those buttons inadvertently and the pad works well enough alongside the Touchscreen, which is suitably sensitive.

Yes, the Touchscreen is highly shiny and becomes "fingerprinted"--of course it does--like most tablets I've seen. Wiping it clear (using a lint-free cloth designed to clean eyeglasses) is easy enough.

And yes, as tablets go this is rather big and heavy--but it's less awkward than I expected. I hope to take it traveling often.

Also, this aside: Yesterday, when I fired this up, was my first-ever hands-on whirl with Windows 8 and I was relieved to realize I could catch on, pretty much, within an hour, though I don't consider myself terribly-techy. The hybrid nature of this little critter and/or Windows 8 must/might be partially behind the double-keyboard effect that distracts occasionally (that I read about somewhere), but I know my confused input, hit-and-missing while learning the new OS and getting used to switching between tablet and laptop modes, caused this weirdness also. Anyway, it's no big deal for me--easy to fix and move on.

Right away I found the hinge mechanism sturdy-enough-feeling and pleasantly-surprisingly easy to work during mode-switching.

The device is too new for me to rate at 5 stars and this 4-star rating is provisional (I didn't subtract a star just for the slightly stiff Touchpad and buttons or glare or smudge-proneness or any weirdness I've mentioned because that's all minor, in my view, considering my purposes); I'm still exploring the features and testing; and I will update this review with further details, probably.

UPDATE February 23, 2015: Finally, I've added the fifth star. I'm still very happy with this and no problems have cropped up thus far.
