Brian ★★★★★ Oct 23, 2026

Swapped out my old full-size board for this 75% and the compact layout is perfect for my cramped desk. Typing feels solid, and pairing it with both my laptop and phone over Bluetooth was surprisingly painless.

James ★★★★★ Oct 22, 2026

The Bluetooth pairing took under a minute and has been rock-solid all week, even with the keyboard sitting a bit far from my laptop. I love that I can switch between my Mac and iPad with one key, and the 75% layout keeps my desk uncluttered without losing the arrow keys.

Miles ★★★★★ Oct 21, 2026

The low-profile switches make a noticeable difference—my wrists don't ache after long typing sessions. The QMK customization was straightforward, and I've already mapped a few macros for work. Solid build, too; no wobble at all.
