Samuel K. ★★★★★ Oct 23, 2026

I’ve been using the 2.4 GHz wireless mode for gaming, and the latency is impressively low. The 60% layout saves a ton of desk space while still offering programmable macro keys. Battery life holds up well even with the RGB backlight on.

Violet B. ★★★★★ Oct 22, 2026

Went from a bulky full-size to this ultra-slim board and my desk feels twice as open. Toggling between my laptop and desktop over Bluetooth is seamless, and the low-profile keys are quiet enough for late-night work.

The 60% layout took a day to get used to, but now I’m flying through macros and custom keybindings. The triple connectivity options mean zero lag whether I’m gaming or typing up reports.
