After installing the drivers through the CD functioned immediately all buttons on the mouse: Zoom, forward + reverse, sideways, and the key with which you can immediately adjust the pointer speed.
The included battery I have now for several weeks and there are still no signs of fatigue.
The range reaches up to my bed loose (2m), all I need anyway.
The only drawback was the mouse wheel button for me. This can not be so easily and smoothly push in as the other keys. But that may be due to my feeling, so fairness not included in my review. Nevertheless, the mouse wheel is much quieter than my old mouse.
All in all a very good value for money. I can recommend the mouse with a clear conscience; )
