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.
