Have the mouse and get it is to be taken without further instruction in use. Batteries pure, USB receiver into the PC mouse to ... done. Works as opposed to other, more expensive wireless mice perfectly. It came in to it now 5 more hours at no Verbidnungsabbruch. Only the unit is a bit too small, here I would prefer a man with a large hand a larger model. Buy, the mouse is worthwhile.
Addendum: More than 40 hours on the clock. NO PROBLEM! Buy recommendation hereby confirmed.
