Julian H. ★★★★★ Oct 23, 2026

The low-profile keys are a joy to type on after years of chunky mechanical boards, and switching between my laptop and desktop via Bluetooth is seamless. Battery life seems impressive so far with the wireless dongle, too.

Aurora Z. ★★★★★ Oct 22, 2026

The 2.4GHz connection has been rock solid for me, no lag at all during long typing sessions. I’m genuinely impressed with how slim it is—it takes up almost no desk space, yet the 96% layout keeps everything I need within reach.

Christopher ★★★★★ Oct 20, 2026

The 2.4 GHz dongle paired instantly with my desktop, and the 96% layout means I finally have a numpad without sacrificing desk space. The low-profile keys feel surprisingly quiet for how shallow the travel is.
