No batteries required
The problem with the wireless mouse is the amount of batteries that they use, and that they always appear to run out when you have not any spares.
This mouse works differently to the rest, by because it comes with its own mouse mat which connects to the computer via the trusty old USB port, the mouse itself actually gets its power through the mouse mat, which is great, no more batteries and never again having to use touch pad or even a wired mouse.
This is ok, but the mat is likely to get on your nerves after while.
