Very good field mouse, precise and light

Some complain of bugs or problems Clicks ... I had absolutely nothing. = /
It works very well, the buttons are well made, and the grip is most excellent.
You can adjust the weight of the mice by inserting weights in a removable cartridge.
Outstanding accuracy, thanks to the laser sensor.

The wheel has four directions (front left rear right) and a middle click. It is also disengageable (deletion of the notches of the wheel) by a close button. Much appreciated on the net to scroll through pages much faster!
3 thumb buttons, two on the index, all customizable (even for multimedia functions).

Driver customizable, you can save the settings in the memory of the mouse, or the PC.
The wire is covered with a black braided; light, it does not bother me absolutely in my movements.
