I have this mouse for over a year now and am very satisfied. The main reason for the purchase was the Nano receiver that constantly remains with me in the USB port of the notebook for me. He does not carry on and stays even during transport in the Neoprenhülle always there without difficulties. If you pick up the receiver, it can be completely submerged in a small compartment on the subpages. Super, I would so otherwise ever lose a part. It lies well in the hand, the connection of the two large touch areas has sufficient pressure and the scroll wheel locks easily but accurately. The reaction of the mouse is very accurate, it glides well on textile substrates, only with high gloss surfaces, the movement is sometimes disturbed. Even with little movement setting precise sampling is possible. The battery consumption is minimal, even if I forget to turn off often, an exchange of the two AAA batteries was only necessary. The mouse is a good Belgleiter on the go, not too big, but also none of these mini toys, which are often offered as a mobile mouse. Conclusion: Quality at a good price
