Back Developed

The predecessor of this mouse I was extremely pleased. The shelf life was still acceptable for the frequent use. Although the new model is still well in hand, but the two keys and the surface of the mouse are now all of a piece. The spring force increases compared to individually set key, what tired in the long run, especially with frequent succession clicking finger.
Unfortunately, once again something Mellow Perfect + has evolved and thereby worsened. Probably because an army of highly paid designers else has boredom. Perhaps the reason is that manufacturers think young people buy only products whose design changes at least every three months. Too bad.
