I need this mouse. It's the only one that lets me work pain free. But I'm on my FIFTH mouse in 6 years. They're extremely fragile. Also, as many others have pointed out, the wireless version suffers from stuttering which can be very frustrating.
If they made a version that wasn't a piece of junk and charged $300 for it, I'd buy it in a second. But of course...they won't. Because we keep buying this one. Very, very frustrating.
