Very cool device! Poor reviews I can not understand.

I have received this device last Saturday and tested it since. The workmanship and quality in my opinion is super. She is very good in the hand and works very precisely. A negative point of the software would have been download, but you is not dwelt latest driver from the Internet to load, I see no disturbing factor or star deduction. If you have the software installed and the mouse worked multiple profiles assigned respectively, the battery lasts longer. Of course, it makes no sense to give full power (maximum dpi and maximum of the signals) and the rum during normal surf the Internet. If I'm wrong with my statements and this should change in the near future I will update my review.

I am very satisfied so far.
