The Microsoft Wireless Mobile Mouse 4000 is a very capable travel mouse that's well worthy of our recommendation. Convenient, versatile and reasonably priced, it doesn't leave much room for complaint.
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
Limited battery life of non-rechargeable AA batteries; Smooth vertical rocker lacks precision
