Summary: This issue has been around for G700 users for years with no solution or fix (even though its rather simple) from Logitech. Very very often this mouse will make the "alt" key on your keyboard get stuck, disabling you from doing a lot of common tasks like typing or doing anything really. Awesome mouse but this bug makes it nearly impossible to use.
Summary: Replaced my g15 mouse. Love the many features on the mouse! Fits well in my hand. The scroll wheel feels solid, not those cheap feeling ones.
Pros: Well design, uses Eneloop rechargeable battery! Can choose to go wired or wireless!
Cons: little heavy, battery will over charge if left in wired mode causing the mouse to feel warm, if battery is taken out in wired mode, a very annoying red blinking light will stay on, no adjustable weights, side grips feel like used low-grit sandpaper.
Summary: Over the years, I've grown used to smaller, less bulky mice, using my thumb, ring, and little fingertips for a claw grip. This is definitely not one of them. The design is ergonomic and comfortable, but it's just too big; when my fingers rest on the mouse buttons, my palm is not even touching the mousepad, as there's just too much mouse for it to get around, and I can't use it as an anchor like I usually do.
Summary: –The cuffs of my shirts often get caught under the flare at the back of the mouse.
Pros: –Wireless/wired convertible transition is smooth - you can even have both the bluetooth receiver and the cable plugged in at the same time with no problems.
Cons: –Not as comfortable as my Razer Naga (old version) - it lacks the support for the right side of my hand like the naga has, which makes me less inclined to use it for >4 hours at a time. The largest problem with it is that my pinky and ring fingers bunch up awkwardly on the side of the mouse (I use a mostly palm grip), but in a claw grip or by leaving your ring finger on button 2, this isn't a problem.
Summary: I work with CS6, CAD or 3D modeling day in and day out, plus play all types of games in my down time. For me this has been a great all around mouse. The design and button placement work very well for my hand and preferences. Around 9 months the Left Click started giving me a problem. I use it a lot but I don't abuse it. (i.e. bang it around.) I bought an MX518 in 2004 and beat it down in UT2k4 for years.
Summary: after about 7 month later, this Gaming Mouse is out of control in a period frequently, so I have to pull the battery out and in again and again in order to reactive this mouse. Two days ago, the left click had new problem. Sometime I just click one time however it shows I click twice. This is strongly affect my when I was doing design and playing games.
Summary: The mouse construction is great and feels sturdy. However, it is made for someone with smaller hands. Anyone with medium or large hands will probably find the mouse uncomfortable after a few hours as it is very small. The big issue I have had with the mouse is the rechargeable battery. It dies after a few hours of game play. This is not normal, and certainly not normal for a logitech mouse.
Pros: Very sturdy, responsive and accurate
Cons: Not great ergonomics for anyone with a medium or large hand (the mouse will feel tiny), The battery dies very quickly, and the charging cable is quite annoying
Pros: Contours are very comfortable, awesome button layout, weighted perfect, wireless tracking is awesome. REPLACEABLE rechargeable battery. For the dough head who said battery life was short. Picked up a 2500mAh and it lasts forever.
Cons: Haven't noticed many. I have this paired with my G13, and although you can save profiles onboard, the computer you are on needs the software installed to get profiles. The mouse IS operational without software though, you just can't adjust settings. Only 30g
