Adam ★★★★★ Oct 23, 2026

Swapped from a full-size board and the 80% layout freed up so much desk space, plus the tri-mode connectivity lets me jump between my laptop and desktop without unplugging a thing. The QMK software took a few minutes to get used to, but remapping the macro keys was worth it for my workflow.

Edward ★★★★★ Oct 22, 2026

The 2.4 GHz dongle is my go-to for gaming, but the Bluetooth switch to my tablet for typing drafts is seamless with zero re-pairing hassle. Mapping macros to the TKL layout took about five minutes and now my whole workflow feels faster.

Steven L. ★★★★★ Oct 21, 2026

Switching between Bluetooth and the 2.4 GHz dongle is seamless, and I love that I can also plug it in when I forget to charge. The macro commands are surprisingly easy to set up and have already saved me hours on repetitive tasks.
