| Pros , different | 8000 Hz polling and 2.4 GHz wireless (maker) Battery rated up to 600 hours Steel plate and OSA PBT keycaps Apex switches in three variants Sibling Ultra 8K boards were praised for value and battery life | Three connection modes: 2.4 GHz, Bluetooth 5.1 (three devices) and wired, with 1000 Hz on 2.4 GHz and wired Muffled sound with little case resonance from layered foam and a double-gasket design (AppleInsider) Thick aluminum shell that XDA Developers says will not move on the desk; Keychron lists 1,724 g PC plate, hot-swap sockets for 3-pin and 5-pin switches, QMK/VIA and a knob Gateron Jupiter Red, Brown or Banana switches come pre-installed on the assembled version 4000 mAh battery, rated up to 180 hours by Keychron |

| Research take , different | A numpad 8 kHz board. Check ZMK compatibility first. | The most complete mechanical 75% in the Q line: reviewers praised the build, the sound and the 2.4 GHz option. The tall caps and fixed slope are the recurring complaints, so a wrist rest is worth budgeting for. |
