“USB is working for me, but I have it plugged in to a USB switcher. I haven't configured the keyboard, beyond the switches in the back. I'm liking the keyboard so far.”
“USB on keeps dropping out, even after firmware update (1.0.2) and reset. Tried multiple computers, windows and Mac. Half the time it doesn’t work at all.”

“Typing feel incredible. My first HE/magnetic switch keyboard and I am completely satisfied. The board itself is heavy and solid. Love the LED lighting. One week in and I'm hooked.”

Keychron Q3 Ultra vs Lemokey P3 HE: your questions
The core difference is in their switch technology and performance focus. The Q3 Ultra uses standard mechanical switches and boasts an 8000 Hz wireless polling rate for low latency. The P3 HE uses magnetic Hall Effect switches with features like adjustable actuation points, rapid trigger, and analog mode for granular control.
No. According to the manufacturer, the P3 HE's hot-swap sockets are compatible exclusively with Gateron double-rail magnetic switches. You cannot install standard mechanical switches like Cherry MX, Gateron, or Kailh on this board.
The Keychron Q3 Ultra claims a significantly longer battery life. Its listing states up to 660 hours with backlighting off, compared to the P3 HE's claim of up to 120 hours. Actual results will vary with usage.
Yes. Both the Keychron Q3 Ultra and the Lemokey P3 HE include system toggles and extra keycaps for both macOS and Windows layouts, making them compatible with both operating systems.
The P3 HE offers more profound typing feel customization through its magnetic switches. You can software-adjust the actuation point of each key from 0.2mm to 3.8mm, and enable features like rapid trigger. The Q3 Ultra's customization is more traditional, relying on swapping physical switches and its gasket mount.
They use different firmware. The Q3 Ultra uses ZMK firmware and is configured via the Keychron Launcher web app. The P3 HE uses QMK and VIA firmware, which are widely supported open-source standards, and is configured via the Lemokey Launcher web app.
Yes, both use standard MX-style stems. However, note that the P3 HE has north-facing LEDs, which may cause interference with certain Cherry-profile keycaps. The Q3 Ultra's south-facing LEDs avoid this issue and are compatible with virtually all keycap profiles.
Both come fully assembled. The Q3 Ultra includes the keyboard, KSA profile double-shot PBT keycaps, Keychron Silk POM switches, and Mac/Windows keycaps. The P3 HE includes the keyboard, Cherry profile double-shot PBT keycaps (shine-through or non-shine-through options), Gateron magnetic switches, and Mac/Windows keycaps.
The Lemokey P3 HE is slightly heavier, with a listed weight of 1910g ± 50g. The Keychron Q3 Ultra weighs 1787g ± 10g. Both have substantial aluminum builds.
Yes. According to Keychron, the Q3 Ultra supports an 8000 Hz polling rate in both its wired and 2.4 GHz wireless connection modes, which is a standout feature for a wireless keyboard.
Rapid trigger is a feature that allows a key to reset as soon as you start releasing it, rather than waiting for it to pass a fixed reset point. This enables faster keystrokes. This feature is available on the Keychron P3 HE, as listed in its specifications.
