When the cute but my first thought. The Microsoft Bluetooth Laser Mouse is quite small. Not for very large hands. It runs very easily and immediately responds to every movement. The laser works on any surface tested. However, the scroll wheel does not work quite as easily and consistently as I'm used to from my previous mouse. It snaps anyway and you can move the scroll in small steps. Somehow unfamiliar, but with long texts and tables certainly not bad. The screen can be controlled as well. The connection via Bluetooth to the PC was done quickly and efficiently. Highly picures. I think I will love them.
