The manual (not need, but who is still dependent must ignore this !!!): First of all, a perfect impression (in detail, perfect German) ... but: The contents of the instruction manual to be 80% wrong and incorrect (particularly the remarks on the power-saving operation, the 20% accuracy refers to the right pictures ... ha, ha) ... so just completely ignore the instructions.
By the way: the mouse (after it has gone into power saving mode) just wakeup a single click.
Nevertheless, 5 stars for the mouse (the fancy manual had minus 5 star worthy).
