Keychron K2 (Version 2) review

The K2 Version 2 is the value pick for people who want mechanical switches on a Bluetooth keyboard. Keychron sells it with its own Super red, blue or brown switches in a hot-swappable socket, so you can change the feel later without soldering. The 75% layout keeps 84 keys, including the navigation cluster that compact boards often drop, and Keychron includes a screenshot key for macOS. It pairs with up to 3 devices over Bluetooth 5.1 and also runs wired over USB-C at a 1000 Hz polling rate, while Bluetooth runs at 90 Hz. The 4000 mAh battery is rated for up to 240 hours of typing with the backlight off. QMK firmware and the Launcher web app handle remapping. The limits are physical: the keycaps are ABS, the plastic version weighs 663 g, and the board sits taller than the low-profile picks here. At $69.99 on sale it still costs less than every other mechanical option on the list.
