The logitech expands on the success of the trackman wheel to bring you the wireless M570, designed to keep you comfortable during all day use.

Another great thing about this wireless trackball is its tiny wireless receiver, the Logitech Unifiying receiver is very small and barely sticks out from the USB port. making it an ideal trackball to be used with a laptop. If you do ever need to remove the wireless receiver it can be stored inside the mouse body, meaning you will never lose it.

The 18 month battery life also means that you wont need to be reguarly changing batteries.
