Very good long-term experience

I have the wireless mouse since 2009, so for 6 years now every day for several hours (> 6 h) in use, and it works like the first day. (Meanwhile will have been improved somewhat safe here and there, so this review is based on the model from 2009 or earlier because I had bought used on eBay)
The ergonomics is undoubtedly excellent. It is quite large, so you need a slightly larger mouse pad, but it is very convenient to use. The hand is completely relaxed after on the mouse in one, my feeling, natural alignment.
With regard to the wireless connection, there is also nothing to complain about. She worked previously always impeccable. The mouse also reacts instantly and there is no re-tightening or identify other conduct of a poor connection.
The keys have a pleasant pressure point - but could be a bit easier, the wheel works flawlessly and has a defined grid.
Battery performance is remarkable, since a charge is seldom necessary. An estimated one in two months, sometimes more, sometimes less often. Unfortunately lacks a display.
The material from which it is made acts from the bottom simple and cheap, the top, however, is beautifully structured. One advantage is that the plastic is not coated with any paint or a rubber sheath. So the rubber cover after a few years was for example. In my former mouse (Logitech MX1000 Laser) sticky. (Also at the diNovo Keyboard selbiges occurred on the palm rest). Since the HandShoe mouse does not seem to be treated with any unnecessary materials the surface is still as good and clean as the first day.
The price is high, but since it is still working properly after 6 years and in my opinion is very ergonomic, absolutely justified.
