The Good BlueTrack technology means the mouse works on almost any surface; suitable for both right- and left-handed users; contoured shape; wireless transceiver attaches to undercarriage.

The Bad Limited battery life of non-rechargeable AA batteries; smooth vertical rocker lacks precision.

The Bottom Line The Microsoft Wireless Mobile Mouse 4000 doesn't leave much room for complaint. It fits comfortably in your hand and works on almost any surface, thanks to Microsoft's BlueTrack sensor technology. It would make a useful addition to your mobile arsenal

The Wireless Mobile Mouse 4000 is Microsoft's latest travel mouse. It offers many of the same features as the Explorer Mini Mouse, but costs about £10 less. This £25 device also uses BlueTrack sensing technology, which lets you use it accurately on a variety of surfaces that a normal laser mouse can't handle. Although less ergonomic, the 4000 fixes several of the Mini's flaws, including the omission of a power-saving off switch and the right-hand-only design.

Plug-and-play design
The 4000's plug-and-play hardware design makes it easy to pair it with a host computer. A small USB-powered wireless transceiver pops out from its hiding spot in the undercarriage, which also houses the power switch, as well as a slot for an AA battery. While we normally prefer rechargeable mice, Microsoft claims the mouse will work flawlessly for up to 10 months on a single battery. The top of the mouse also houses a small red LED that alerts you when battery power is low. Microsoft offers the mouse in five colours: blue, pink, green, black and white.

Microsoft includes its IntelliPoint 7 software for both PC and Mac. You'll find settings for button assignments, and scroll and click speed, as well as help files, in an easy-to-use program. If you don't have the CD with you while you're travelling, you can still use the mouse with your computer's internal settings -- no external drivers are required.

One of our major complaints with the Mini was its right-hand-only design -- its contours made it uncomfortable for lefties to use. Thankfully, the 4000 is symmetrically shaped, making it equally easy for left-handed users to scroll and click the four buttons. The entire mouse is covered with soft textured plastic for extra grip.
