The new optical versions add the latest technology to the unique design of the original Perfit Mouse. A high precision optical sensor provides excellent cursor control. The Perfit Mouse Optical (PMO) places a scroll wheel above the thumb support, rather than on the top of the mouse to reduce the strain on the index finger, which is already heavily used for the primary mouse click.

The second problem is dust and dirt. It’s amazing how quickly it builds up inside the cavity where the mouse ball sits in normal operation, and unless you clean it out very regally, the pointer will not move evenly across the screen as you use the mouse.
So, Microsoft being the innovative and creative (ha!) people that they are, they have come up with the Microsoft Wheel MouseOptical, available almost everywhere for about 25 quid.
