Philips SPM 9800 Bluetooth Notebook Mouse (Wireless with 360 degree TouchControl, laser sensor, USB 2.0) Silver (accessory)
The mouse works quite well so far, and the 360 ° mode. However, I do not have the impression that the mouse works better than a regular optical mouse (on different surfaces). Negative points: - Not particularly ergonomic, but you can see that, yes.
