Manufacturer description

The Lenovo 300 Wireless Mouse is a pocket-sized 2.4 GHz mouse built for people who work away from a desk. It tracks with a 1000 DPI optical sensor, which is enough resolution to move cleanly through spreadsheets, slide decks, and long documents without the acceleration wobble you get from a trackpad. The ambidextrous shell works the same in either hand, so left-handed users are not stuck with a right-biased grip, and the compact body drops into a laptop sleeve or jacket pocket instead of taking up a full accessory slot. Setup is a plug-and-forget affair: the nano USB receiver stays seated in…

Frequently Asked Questions

How long does the battery actually last?

Lenovo rates it at up to 12 months on a single AA battery. Actual runtime depends on daily hours and surface, but there is no charging cable or dock to manage.

Is this mouse good for left-handed users?

Yes. It uses an ambidextrous design, so the shell is symmetrical and works the same way in either hand rather than being contoured for a right-hand grip.

Does it connect over Bluetooth or a USB dongle?

It connects over 2.4 GHz wireless using the included nano USB receiver. You will need a free USB-A port, or an adapter if your laptop is USB-C only.

What DPI does it track at, and can I change it?

It uses a 1000 DPI optical sensor. That is a single fixed setting suited to office and travel use, not a multi-stage DPI switch for gaming.

Will it work with my Mac or Linux machine?

Lenovo lists this mouse for PC and laptop use with Windows. Other operating systems are not specified, so check the product listing for current compatibility details.
