The big problem is the very low battery life. During gaming or heavy use of is in fact empty after 5 hours. The included USB charging cable is not a real solution. So you can Although the mouse during charging still use but the cable is thicker and therefore stiffer than a normal mouse cable. The mouse can be used only conditionally with the USB cable, the mouse is then considerably less smooth rolling.
The included battery has 2000 mAh (which is not exactly a great deal is by today's standards). I now use more battery (2600 mAh and 2200 mAh) and hope this change and to charge the batteries then in a separate charger.
