Our take, based on research
A solid low-profile aluminum 75% for wired use. Pick the hot-swap version if you want to change switches.
Overview
The S1 is Keychron's low-profile aluminum 75%. Keychron's page lists a CNC aluminum body with a steel plate, a tray mount, Gateron low-profile MX switches, low-profile LSA double-shot PBT keycaps, a north-facing RGB option and 960 g. MakeUseOf reviewed the hot-swap RGB version and found the typing smooth, with a maximum rear height around 25 mm with keycaps. How-To Geek highlighted the weight, the CNC 6063 aluminum body and the lack of the hollow sound that other compact boards give off, and noted VIA support and a Windows and Mac layout. Keychron also sells a version without hot-swap sockets.
