I had previously been some billg-drahltlos mice in combination with wireless keyboard, which only cost half as a complete package (mouse and keyboard) from this mouse, but worlds better functioned. Even the insertion of the batteries was because they have to be threaded into a depression for a challenge and this is then the contact wire extreme bends. Mir without cross Ulich how to construct something. After about half week use showed the same problems as already described by the other: the mouse reacts extremely delayed, jerky, and can be very difficult to click. That they would supposedly as announced in the advertising film usable on any surface, I think is the purest bullshit. Even on nichtspiegelndem ground and even on a Mousepad jerky mouse extreme. I will send them back immediately.
