Is the 8,000 Hz polling rate worth using?

Only if your PC can keep up and you play fast-paced games. At 8,000 Hz the battery drains much faster, so many owners drop to 1,000 or 4,000 Hz for everyday use.

Can I use it with a laptop over Bluetooth?

Yes. It pairs over Bluetooth as well as 2.4 GHz and wired USB, so one mouse can serve a desktop and a laptop. Bluetooth runs at a lower polling rate than the 2.4 GHz dongle.

How long does the battery last?

Keychron rates it at up to 67 hours, which assumes a lower polling rate. Expect noticeably less at 4,000 or 8,000 Hz.

Which sensor does it use?

It ships with a PixArt 3950 or 3395 sensor, both capable of up to 30,000 DPI. Either is more resolution than most players will ever use.

Is it good for office work as well as gaming?

Yes. The light body and Bluetooth make it comfortable for desk work, and the high polling modes are there when you switch to games.

Does it work while charging?

Yes. The wired USB connection lets you keep using it while it charges.

Our take on the Keychron M4 Wireless Mouse

The Keychron M4 is an ultra-lightweight wireless mouse built around a PixArt 3950 or 3395 sensor, with DPI up to 30,000 and a polling rate up to 8,000 Hz over its 2.4 GHz dongle. It connects three ways: 2.4 GHz, Bluetooth, and USB wired, and Keychron rates battery life at up to 67 hours. That puts it in the same class as other sub-60 g esports mice, but with Bluetooth and multi-device switching that most competitive mice leave out. It suits gamers who want a light, high-polling mouse and desk workers who want one mouse for several machines; buyers should know the 8,000 Hz mode drains the battery much faster than the rated figure.
