SpecPicks Verdict

SpecPicks scored Lenovo 300 USB wired computer mouse using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming peripherals category. Lenovo's gaming peripherals lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions

What DPI does the Lenovo 300 mouse track at?

It uses a 1600 DPI optical sensor. That resolution is fixed -- there is no DPI-switch button on the mouse to cycle sensitivity.

Is the Lenovo 300 good for left-handed users?

Yes. It is a full-size ambidextrous design with a symmetrical shell, so the grip is identical whether you use your left or right hand.

Does the Lenovo 300 need software or drivers?

No. It is a USB-A plug-and-play wired mouse -- connect the cable and the three buttons plus clickable scroll wheel work immediately, with no setup.

How long will the Lenovo 300 mouse last?

Lenovo rates the microswitches for up to 20 million clicks, the left/right buttons for up to 3,000,000 clicks, and the scroll wheel for up to 1,000,000 clicks.

Can you game with the Lenovo 300 mouse?

It handles casual gaming at 1600 DPI, but at 120g with only 3 buttons and no adjustable DPI, it is not built for competitive FPS play.
