The Logitech VX Revolution is a portable laser mouse that, because of its small size, is designed for laptop use while maintaining many of the features found in desktop mice. One of its most notable features is its MicroGear Precision Scroll wheel that can be set to two modes of operation from a switch on the bottom of the mouse. In the first mode, the scroll wheel operates with detented action (typical clicking scroll action), and in the second mode it operates in an almost frictionless fashion. In the frictionless mode, the scroll wheel keeps spinning when flicked, allowing you to very quickly scroll through large documents, and lists.
The VX Revolution includes a high-resolution laser engine for accurate tracking on almost all surfaces. It also includes a click-to-click scrolling function as a new method of scrolling through lists using mouse clicks. It operates wirelessly on a 2.4 GHz frequency with the USB transmitter/receiver dongle tucking away into the mouse itself when traveling. Reviews have suggested that you can get up to an 80 ft. (24 m) range from the dongle.
This mini-mouse weighs 4.2 ounces (119 g) and is about the size of a bar of soap. It uses a single AA battery (included) and features an LED battery life indicator on the mouse. Expect to get approximately 120 days use on a single battery. The package also includes Logitech's SetPoint software. The original retail was $79.99 for the VX Revolution when it was first released in August 2006, but you can now find it for $50 - $65.
The Logitech MX Revolution is the desktop version of this mouse.
