I did not put 5 stars because the mouse has a defect anyway light for my taste, this mouse is light which is very class, the Razer logo appears good but the keypad that it also heats on 3 top buttons (this must be nice when it's cold but otherwise I find annoying asser) after can be remedied by turning off the light of the mouse (it is possible to keep the power on and Razer Logo disable the light-Pad Digital / mouse wheel)
