Summary: the 8200 dpi is just to much and not needed. if you are looking for a gaming mouse go buy a razer deathadder because it is cheaper and has better brand to back it up.
Pros: Nice mouse and has a very nice feel. The button to change dpi on the mouse is quite nice.
Cons: The first one i bought the scroll wheel took a poop and i couldnt scroll with it and still cant. i bought another one because i didnt want to get used to a new mouse and it has been working fine for over 5 months now.
Summary: do to it being for left and right hand when you use side buttons my fingers tend to squeeze the buttons on opposite side of mouse and in game it will make you shoot,crouch,cast spell etc. and be become a pain to deal with.
Pros: very responsive Easy to setup with on the fly DPI adjustment good weight once weights are installed changeable bottom plate for smooth movement on different surfaces
Cons: Bad button placement (always hitting buttons on right side of mouse) not very comfortable for long gaming sessions
