Good DPI ; Smooth ; Fast ; Fits in hand nice ; Wired

Second one of these, that has stopped working. Each one of them has died in 12 months or less ; The plastic ends up wearing out on the tact switches inside of the mouse, that is the reason for it not clicking all the time anymore

Ease of use, quality materials, Logitech reliability

A touch on the small side, low refresh rate somewhat unsuitable for pinpoint FPS accuracy, ambidextrous design doesn't lend itself to ergonomics

Cheap, Ability of scroll wheel to tilt to either side and be used as buttons is a nice feature, response is alright

Cheap build quality

I have a small hand, even for a woman, this mouse fits without me feeling I have gripped a big rock. My hand never tires even if used for hours. It tracks great and while it does pick up fingerprint residue, it cleans up great with a quick wipe. It's...

Looks big, but fits my small hands like it was taylor made. Works with KVM switch, no problem. Logitec set point 4.80, nuf said

Has wire, but if I ever find a wireless keyboard and mouse that plays well with a KVM switch, I'll marry it

Got this to replace an old logitech mouse that had scrolled too much. Love it! Its very smooth and quick

none

short throw... the mouse gets you a good distance on the screen with just a flick of the wrist. It's a very accurate mouse and optical so you don't have to clean it all the time..I pair it with a Corepad Victory mouse pad for the best gaming.. It's...

it doesn't wear out!!...darn
