I really liked it and bought it a couple of weeks ago, however I've run into a deal-braking bug and with no possibility to report a bug (the website is extremely slow and barely loads most of the time), I kinda ignored it since then.
In Firefox on Android, I can't type a secondary character (e.g. "p") as first character into the address bar. Double tapping y/p results in "yp" instead of only "p". It works everywhere else, but not in this specific text box.
Also, somewhere in the docs it's mentioned that you can use one of the outer buttons as trigger for a secondary char (i.e. quickly tapping "o/y" should result in "p"). I couldn't get this to work even once.
I agree the value proposition of alternative layouts is a bit shaky for small touchscreen keyboards. It's not obvious one does enough typing on them to offset the switching cost. (As opposed to physical keyboards where a more ergonomic layout is a no-brainer.)

That said, I have had good experiences with switching to an even more radical layout: https://entropicthoughts.com/learning-keybee
