The battery life is incredible, had previously never change, even though I usually do not turn off the mouse on the switch.
Clever on the mouse is the Nano receiver that, if he does not inconspicuously inserted in the laptop, can be stuck purely in the mouse. Also nice is that the mouse is not a red illuminates from below, but really only works with UV light.
Unfortunately, the mouse looks a bit cheap, but what thou.
All in one a good mouse with a great price-performance ratio, I can only recommend. Have now 2 of them.
