In case of occasional work on artwork I know nothing negative noticed on the resolution and sensitivity. On the contrary, the setting possibilities are numerous.
The processing of the mouse makes a good impression. for example, the cord is nice and long and protected with flexibilem braid. The lighting effects I like and the main elements (LB, wheel, RB) are reliable. Just use the mouse wheel I had with other mice problems with the (non-existent) screening or rotational resistance.
I can not fault only:
-The side buttons (explorer next, previous) are not programmable
-good that there are 3 central function keys, but you have already craning to reach them ...
-The Laser does not respond to any real support, as one would expect of infrared mice. And I do not mean the color of the background, but the structure. I suppose that the laser shuts down on complicated ground rather than send jerky or lack positioned information
-really annoying is the occasional pinching the middle mouse button. Also can not be Reset as fast. No idea how that comes about
