So they're good? Even though they're, like, domes?
They are very good for domes, one of the most tactile ones out there! All for a fraction of the cost Realforce and other Topre boards are. Of course there are other great dome and slider keyboards but they're harder to find. Such as the Qtronix Scorpius, etc.
Chryos has done a video review of his BTCs boards before too, you could find it on his channel somewhere!
