I have a Clicks Keyboard and love it. As far as I can tell the team behind the Clicks are pretty intertwined with https://www.fxtec.com/ - in that FX Tech staff seem to be involved in Clicks support, etc.

The Clicks Keyboard for iPhone (14) was a great concept, and pretty well executed for a V1 - I haven’t tried their follow-up devices.

But assuming it’s the same team, there’s a history of shipping devices behind them.

(That isn’t to encourage you to pre-order! Just to perhaps contribute some more optimism to your hope that they succeed)
