Very good mouse with a beautiful design, very good handling, I was very surprised, it changes my basic mouse I had before for 3 years! This is my first purchase of a gaming mouse and I must say it is really bluffing, especially in terms of its comprehensive programming and sensitivity! No need to go from one end to the other of the screen! It is a very good mouse, its drivers are not provided with it must go to the razer site in the support section. I am very satisfied with my purchase and Amazon, to buy emergency!
