Selling Points
The overall feel is relatively heavy, similar to a "black switch". Pressing it feels soft yet solid, with a distinct tactile bump at the bottom-out point. The travel distance is short, the actuation is fast, the sound is relatively quiet, and the feel is focused yet not harsh — making it a heavy-press linear switch.
