| Pros , different | Springy, quiet scissor keys (WIRED, Tom's Guide) 75% layout in a thin board that fits in a bag Tri-mode connection with Mac/Windows layout switch and ZMK firmware support (Tom's Guide, Keychron) Rubber feet and a comfortable fixed angle (How-To Geek) | 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 |
| Cons , different | No backlight (WIRED, Tom's Guide) Plastic body; Tom's Guide found it a little heavy for an ultra-slim board Cheap-looking cable and dongle, and not compatible with Android (Tom's Guide) WIRED noted the physical mode switch is easy to knock when the board is tossed in a bag Scissor keys are fixed; no hot-swap and no NKRO listed | No adjustable feet; the angle is fixed at 5.2 degrees (AppleInsider) Wirecutter criticises the tall keycaps and the steep, non-adjustable case slope Keychron's 1000 Hz rating applies to 2.4 GHz and wired; the sibling Q1 HE drops to 90 Hz on Bluetooth (Tom's Guide) Heavy at about 1.7 kg, so not a portable 75% Wirecutter notes it costs more than its own upgrade pick, and AppleInsider's headline calls it costly |
| Research take , different | A well-reviewed, inexpensive productivity board for people who like low-profile laptop-style keys. If you need backlighting or mechanical switches, look elsewhere; the B3 Pro is the closest sibling with Launcher support. | 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. |
