In layman I put the USB receiver to it and follow the mouse turned on and nothing went.
Receiver was recognized by Win but not mouse. After unsuccessfully I wanted drivers, battery etc. have tested, I concluded the mouse to other computers in my area. No Function.
Returns and exchanges folded exquisite, Amazon Thanks!
New mouse came pretty quickly and it was like in my imagination:
Unpacking - Insert> Receiver - enable> mouse -> Works!
Nevertheless, a small flaw I could find. Even compared with the defective mouse has the funktionierene significantly fairer clicks. Is a bit annoying, but hopefully soon forgotten.
