The mouse is powered by two AAA batteries with a lifespan of several months, and there is a low-battery indicator. Communication with the PC is via Bluetooth; Microsoft supplies a dongle that establishes communication instantly and can also serve as a universal adaptor, with the same driver requirement as for the 8000 desktop model. Of course, if your notebook is Bluetooth-equipped, you won't need the dongle, since the mouse will operate without it. Here, recognition works the same way, with a button to start detection and a flashing light to confirm it. The advantage of Bluetooth is obvious, since with it you can be up to 20 feet away when using the device as a remote.

For once, packaging is put to good use: the transparent plastic receptacle shows both sides of the mouse. Once you take it home, the receptacle can be used to carry your rodent and the dongle, and there's even a carry strap.

A Real Little Heartbreaker

The sensor is Microsoft's own 1000 dpi laser model, and in use, I found it to be every bit as precise as its desktop big sister. The reactivity is perfect for use with a portable computer, and fluidity just as good. This is the most reactive and precise notebook mouse to date. I have to admit that I was totally charmed by this multiply-clever little mouse - it's both seductive and convenient to use.
