Nothing of note

Computer mice are easy to take for granted. Very rarely do people gloat about the power of their mouse like they would about a processor or graphics card, even if they have a nifty device like the Hillcrest Labs Loop Pointer or SideWinder X3 from Microsoft .

Works very well for a basic mobile mouse; Excellent tracking; Comes in five different colors

Not many exciting features; Dull design

The Wireless Mobile Mouse 4000 is Microsoft's latest travel mouse. It offers many of the same features as the Explorer Mini , but does so for $20 less. This $40 device also uses Bluetrack sensing technology, which lets you use it accurately across a variety of surfaces that a normal laser mouse just...

The stand out or rather, the most important feature of the 4000 is the inclusion of the Blu track sensor. This technology has given the 4000 the power to operate on any kind of surface where most mice would fail.

The Microsoft Wireless Mobile Mouse 4000 is a small mouse designed to be used with netbooks, and features Microsoft's BlueTrack technology which is designed to offer superior accuracy. The Wireless Mouse 4000 is a little mouse who makes its motion simple.

This mouse is very good. It has multiple programmable buttons and good battery life plus it's wireless. I would recommend it to anyone looking for a reasonably priced mouse.

Very Responsive; perfect size; wireless range

nothing so far

This small but perfectly formed mouse from Microsoft is designed to be used with a laptop computer. To that end it's slightly smaller than the average desktop model, and its tiny USB receiver fits neatly into a slot on the bottom when not in use. That said, it works just as well with any desktop PC.

Designed for laptops and computing on the go, Microsoft's Wireless Mobile Mouse 4000 is small and comfortable to use.
