Microsoft Comfort Mouse 4500

Good to know:

BlueTrack Technology
Allows you to work without problems on surfaces that are unacceptable for conventional devices, such as carpeting or upholstery of upholstered furniture.

From the press release:

Microsoft continues to develop a line of products that support the original BlueTrack technology. Recall that such devices differ from all similar products in the use of an advanced optical sensor with blue backlight, which provides a more accurate reading of the working surface than mice with a laser or standard optical sensor. Thanks to new technology, mice are able to work without problems on surfaces that are unacceptable for conventional devices, such as carpeting or upholstery of upholstered furniture.

The Comfort Mouse 4500 is the first wired device with an optical BlueTrack sensor, for those who don't like to charge batteries. Like the rest of the BlueTrack mice, the Comfort Mouse 4500 will work on almost any surface (excluding mirrors and glass). Also, the novelty is equipped with five programmable buttons, an omnidirectional scroll wheel and is backed by a three-year manufacturer's warranty and has several colour options. In addition to classic black, there are pink, red and blue.
