Respectable gaming mouse

This gaming mouse is really the value 25, which you have to lie down. The mouse can be divided into 6 different easy to change dpi - lead modes and is my opinion (at least for right-handed) very comfortable to hold. Very good price / performance ratio. 9 years ago I bought the previous model (also x7) and was very happy - she still works today - now I want to see how long I have this.
