Summary: All in all, a decent mouse. I used it for three years before giving up on it and replacing it. The left and right buttons would double click half of the time when I was trying to double click, even after trying to clean or mess with clicking settings in Windows.
Pros: Can be used on many surfaces. Mouse wheel has that ratchet-like scroll to it. Not too small.
Cons: Mouse wheel started squeaking about 6 months into using it. Left and right buttons work intermittently after about 2 years of use.
Summary: This mouse feels very lightweight and cheap, and that's because it is. The mouse will eventually start to cut out and just die. I thought it was the batteries but when I switched them out for new ones the mouse's performance didn't improve.
Summary: The sad part is - - - - for another 5 or 6 bucks, I could have actually bought a quality Logitech or Microsoft mouse. . Lesson Learned.
Pros: This has got to be the most pathetic, low grade, piece-of-junk mouse that I have ever had the displeasure of wasting my hard earned money on. I have had this mouse connected to my PC for pproximately 2 ½ hours and it is no longer working! I have replaced the batteries, unplugged and re-connected ...
Pros: This is a good mouse. I've had it for going on four months now, no problems. I use it on multiple surfaces at work and at home (white laminate/black wood/bed sheet). I also toss it in my laptop bag every morning and every evening since I take it back and forth. No problems whatsoever. Feels good ...
Summary: I used this mouse HEAVILY for gaming on the road from September of 2012 till recently when I got a job that let me stay home. Buttons all still click like new, no noticible wear, mouse wheel still works great, dropped many times in airplanes and no damage at all. Very durable little mouse.
Pros: Not too small, great ergonomic grip, nice little magnetized slot to put the dongle when you are not using it so you don't lose it. Oh yeah, small dongle so you don't break it off accidentally.
