This mouse is slightly smaller than a full size mouse but it does work great on many surfaces. The small usb adapter is great since my housekeeper kept breaking the larger adapters found on other mice while cleaning my tower. The mouse does have a spot for storing the adapter when not in use. It also comes with 2 batteries. I like the fact it also has an on/off button to conserve battery life.
I bought this because of the small USB plugin, and have been using it last 2 weeks.
This mouse stuck from time to time, quite often. I replaced with new batteries but still having the same problem.
