Currently using a new computer mouse. Model designation of logitech product is " VX 450 Nano". It is a cordless laser mouse. I have a tiny little usb nano receiver, plugged into usb port. Both devices are co-operating. The little receiver only sticks out about half an inch.
The laser mouse seems accurate, either on bare timber of the office desk or on mouse pad. I experimented on a sheet of glass, and the accuracy was reduced severely. It definitely does not respond on a glass surface. But on the mouse mat, or a polished timber surface the reaction is acceptable. Two AA batteries are required. Software can be downloaded from logitech site, if the user prefers extra features.
