Been 6 month's and not one problem the off switch help's use this 12 hours a day.The batteries lasted 4 months of couse i forgot to turn it off several times.So you could get 5-6 months,I really like this mouse been flawless no cable.


Smooth motion trackball The quiet click is very quiet



Seller has a rare (unusually rare) shipping issue, but I'm fine he solved, great seller will use again




I got this guy because I was having wrist pain and I have to say that I think it is working! My hand seemed to slide onto it without much of a learning curve. The button configuration works well with the middle click being an added bonus.

My wife has small hands and likes this mouse. I don't...it seems to make my hand/wrist tired where my normal Logitech mouse does not.




I have roughly 150 of these in use that I have used to replace ball mice. I have had no complaints. The predesessor to this mouse had the issues where it needed unplugged and plugged back in to function properly, but that has not been the case with this one. Has been used with Windows XP, 7 Pro 32-bit, 7 Pro 64-bit, 8, and 8.1.

This mouse is good, I paired it with K800 keyboard, it feels amazing in your hand and the buttons are placed well, wheel has a button to roll free or with some resistance.
