Background and Identification

The Logitech Anywhere Mouse MX is a laser mouse released in 2009. The mouse uses a small Logitech Unifying receiver to connect to your computer. If you lose this receiver, you can order a new one from Logitech or Amazon and pair the mouse using the Logitech Unifying software and following these simple instructions.

The mouse is powered by two AA batteries. Slide off the bottom panel to replace the batteries (reportedly they last anywhere from 4-18 months depending on usage) and to stow the USB receiver in a safe little cubby for travel. Since the mouse uses Logitech’s “Darkfield Laser” technology for tracking, it can work on glass tabletops without a mousepad.

The scroll wheel allows for horizontal scrolling when it is nudged left or right and can toggle between smooth scrolling and ratcheted scrolling when it is pressed. The mouse also features two thumb buttons on the left side (sorry lefties!) which move forward and back in web browsers and other applications.

The Anywhere Mouse MX is designed to be small and portable and is 3.5 inches (8.9 cm) in length. You can identify the mouse by looking for the words “Anywhere MX” printed on the underside.

The most common issue reported with the Anywhere Mouse MX is that, after some use, a single button press will result in multiple registered clicks. You can diagnose this issue with this simple tool: watch the bottom gray bar to see how many clicks are registered each time the left or right mouse button is pressed or released. Follow the guide on this page to fix this annoying issue.
