This is a good-quality basic optical corded mouse, whose cable retracts and rolls onto itself and plugs directly to the computer through the USB port connected to the cable. No dependence on batteries, which is always great when travelling to remote areas of the world. This mini does the job and, most importantly, is the most portable mouse I have ever had. It looks like a toy!
On the other hand, it is so tiny that I don't find it that comfortable to use, even though I have very small hands. So nothing you want to take with you if you are going to use your computer all the time and need a comfortable mouse with more functionality. If you use your computer just for a few emails and general browsing when travelling, this mouse might be for you.
