Summary: I got so tired of cleaning the trackball mouse. This is such a wonderful replacement for it. It's the perfect size. It glides smoothly on a mousepad or desktop. Plug n play made it a breeze to switch to the USB optical mouse.
Small and convenient for carrying in my bag. Great accessory.

Summary: Great addition to my Dell laptop. It's small enough to carry in my bag and works just like a normal mouse. No battery required. It has a red optical light that works on the table. Just plug it into the usb port and Windows 7 pro recognizes the mouse and is ready for use.
