The K3 is a low-profile 75% and only takes slim switches; the KS-33 Red is the go-to budget low-profile linear — factory lubed and smooth, a clean upgrade path for this portable board.

Non-standard stabs prevent most third-party keycap swaps
Keychron K3
Keychron · keyboard
The K3 is one of the few low-profile 75% options out there, especially for ISO-CH layouts, which is why people end up with one. The downsides hit later — non-standard stabs that won't take third-party caps, and stock ABS that goes glossy fast. Some owners stay happy with it as a portable; others regret it once they see what else is out there.
