For Mouse: The pretty LED lighting does not stop me from, to investigate the functions of the keys. On the left, are two separate outgoing keys. These are used for example on websites to pages to go forward or backward in the course. In games it can be configured securely so that it can function as the weapon swap perform loose. A very useful feature but at first habituation thing, because these keys of gross motor Rikern as were like depressed me even accidentally, until I got the hang out.
The mouse wheel acts meanwhile are quite "relaxed" posted. I do not mean that at any moment one would have scared the mouse to have to reassemble, no, it's just very easy to move. Feels not particularly high on the mouse but since otherwise really looks great, there's no point deduction. So remind me that mouse, by design, to 100% of my old Razer mouse, I sometimes for five times bought - this copy is likely to be the feel good being certainly bearable;)
Lastly, there are behind the wheel a small button that you can adjust the DPI numbers. At what stage it is, you realize this very quickly, because the mouse always feels much brute fine or up to the last stage.
Finally, after being actually reviews about mice writes a conclusion: This mouse does exactly what it claims to be. Full satisfaction!
