Lenovo 400 Wireless Optical Mouse

The Lenovo GY50R91293 is a wireless optical mouse that gives you reliable control without weighing you down. It links to your laptop or desktop through a nano-size USB receiver on the 2.4 GHz band, so you get an immediate, steady connection the moment you plug it in.

Inside, a 1200 DPI optical sensor keeps the pointer moving exactly where you intend, making everyday tasks like browsing, document editing, or spreadsheet work feel smooth and predictable. The primary buttons are engineered for up to eight million clicks, which means they can handle heavy daily use in the office, the classroom, or on the road.

At about 65 grams, the mouse feels light in a backpack yet solid in the hand. Its shape supports both left- and right-handed users, so you do not have to think twice about comfort when sharing it with a colleague or family member. Because the single AA battery can last as long as twelve months, you can travel or commute without packing spares.

Setup is as straightforward as it gets: insert the receiver, power on the mouse, and start working. Whether you are finalizing a deck in a coffee shop, navigating a conference room display, or managing emails from the couch, this mouse delivers dependable performance wherever you open your laptop.
