A really necessary purchase, Im glad I found this product.
Before this mouse I had x7. If you play games in games and you had another mouse and changed to this one. Then you will not have to get used to it for very long because of the Hyper x program. (read in Pros).
Pros
1. Hyper x.
2. Build quality (as always the best).
3. Backlight ))
4. Just an INCREDIBLE program that probably changes everything. If you had some kind of mouse from some company - on which you can’t even see the DPI (mouse sensitivity). Then on this one you can configure absolutely any DPI, at least 400 at least 100 at least 6400.
