Mice are a matter of taste, yes, no question that personal desire ergonomics is very tricky, so to evaluate empirical values always individual. Two things, however, interfere clearly also intersubjectively comprehensible: 1. the high resistance of the left-hand buttons (completely unnecessary this problem, restrictive and comfort even at low rodents to realize there is often no problem) 2. Pressure points of all keys (never clearly defined, but soft and even unnecessarily long)
I give the mouse a buddy, a MMO gamer, and try my luck at another.
