i got this mouse and its been nearly a year i'm using it,, no issues at all.. works just fine,, i do a lot of animation, modelling, compositing and editing,, use it ruff most of the times and always stood by me,, got this from the local market for 220 bugs..
To begin with its a very nice and worth buying. But its not long lasting and the sensor and mouse wheel button goes malfunctioned!! until u use it carefully.Do not just throw it like garbage..just keep it as it shoud be and u r good to go... Overall worth the price..
