Sides are rubberized. On one battery (AA). One button on the side, four-dimensional wheel. There were some two disks with programs with me, because. I"m sitting on linux - I threw it out as unnecessary. About dpi on large screens. Tested on 23 "and 12" - everything is ok. Didn"t do any settings manipulation. I don’t know about games, I have enough for strategies. In general, a mouse is not a video card, you have to feel it yourself in the store.
