I have had the mouse for almost 1 year and never had problems. You will use the notebook, which is usually at home. That's why I did not want such a miniature mouse. The Cherry lies comfortably in the hand and is for my occasional transports in no case too big. The build quality is stable and comfortable handling. Until now, the battery had to be changed once. The on / off switch on the bottom is for power saving genuinely useful. I also think this little receiver very convenient. It falls on the notebook and the notebook hardly fits with receiver in the pocket. The fact that the mouse is ready for use immediately on any device, we have our already often plugged into "guest" notebooks in order to work more easily turn to. The touchpads are only a temporary solution for a short time for me. Very important were my thumb buttons, especially the back button, and the scroll wheel. The transmission is running smoothly (no hook, no jerking). Who transported his notebook not only in a narrow shell, can safely access and gets a comfortable, reliable mouse.
