Excellent for hand mouse / RSI!

For 4 weeks, I had pain on my elbow, the clicks have easily hurt (I spend 12+ hours a day on the PC). It has not gone away, so I'm the doctor who told me that I should still in addition to the prescribed bandage and cream to buy a new, ergonomic mouse, which will cost around 150.

The products of the "big brands" I have watched with great disappointment, because they were just ugly and impractical for my design activities. After a long search I found this mouse, and did the testing.

Pro:
+ Very ergonomic "grip"
+ Very short Anwöhnungszeit
To change + 3 speeds fast (fast for browsing, slow for prezise curves in the design)
+ Well weighted wheel and ordinary control buttons (no billges operation feeling)
+ Matte surface (when the hand sweats, slips / it does not stick)
+ Nano Receiver

Cons:
- Automatic hibernation: if you do not use the mouse for a few minutes, it will be deactivated. Reactivate it with a simple click, but that would not necessary
- The mouse is somewhat large and could be used for people with small hands a problem (I have big hands)

In general, I am very pleased that I will keep your mouse. After approximately 10 days use my pain has already become much smaller and I can work more relaxed again.
