This is a short recession, because it was already reported in detail about the positive aspects of ergonomics. The only thing that bothers me and what is the reason for only one star that if I spend nearly 80 euros for a mouse, then this should also be of higher quality. After only a few months, the coatings are replacing several site on the surface .... that's not at all. The build quality is absolutely bad and I would have to buy a Ergo Mouse for 20 Euro.
