good for nothing - keeps losing connection

At first I was convinced - little mouse, small price, quickly connected.
But after> half a year, the problems of the mouse make increasingly apparent:

(be my "conventional" wireless mouse have not yet changed) multiple battery change: the first major problem

second major problem - ever the mouse loses connection to the laptop, which is resolved only through gesture on the touch panel and then move mouse (impractical, if one uses the laptop over a larger distance with the mouse (the supposed inter alia, the purpose of a wireless mouse be).

And so I would be already talking about the third coarse gripe - the scope: short and sweet: ridiculous, even less than "conventional" wireless mice with dongle.
