Eli F. ★★★★★ Oct 23, 2026

I've been cycling through all three wireless modes and the 2.4 GHz connection is rock-solid with zero lag during gaming. The QMK software made it easy to set up a few custom macros for my video editing workflow, which saved a ton of time.

Claire J. ★★★★★ Oct 22, 2026

The 96% layout is perfect for my desk—no numpad sacrifice, but it’s still compact enough to feel tidy. Switching between my laptop and desktop via Bluetooth has been seamless, and the QMK software was surprisingly easy to set up for my gaming macros.

Finally being able to program custom macros per application is a game-changer for my workflow, and the 96% layout means I don't lose my favorite keys. The Bluetooth connection has been stable for hours of uninterrupted typing.
