Keychron J2

The J2 is a wireless 75% with hot-swap sockets. Keychron's page lists double-shot PBT keycaps, 2.4GHz, Bluetooth for three devices and wired, 1000Hz polling over 2.4GHz and wired, QMK with Launcher, 22 backlight effects, 808 g and a 4000 mAh battery rated at up to 300 hours. GamepadSquire's review praised the multi-layer foam and the sound, the QMK support and the 83 keys with a knob, and noted drawbacks: an ABS case with some cheaper-feeling sections and a slightly hollow spacebar, a tall profile where a wrist rest helps, and no physical Mac and Windows toggle. Keeb-finder compared it with the J5 and J4 and listed three typing angles (4.5, 6.4 and 8.8 degrees), a receiver storage slot and sidelight bars. That site is thin on measurements, so treat these as one reviewer's view.
