Positive:
+ Have the mouse for a few weeks and it works without problems! (I understand you need for each mouse a smooth surface, and it works just like an expensive this also)
+ Inaccuracies I notice anything, quite the contrary. Previously had a favorable Hama mouse with cable that is much less accurate than the Logilink!
+ They got to about 6 meters tested and it works !!!
+ Price (When I think that I have to throw away an expensive battery mouse after 3 years, because the battery can not be replaced without the mouse to break anything, this mouse is worthwhile even if it comes after a year break!)
