Have been using the UT22 with the Taipo layout for a while now and am very happy with it. (Nowhere near my usual speeds yet, but very usable for recreational purposes!)
The case is Bubbleology’s own closed-source design, which he kindly allowed me to get printed.
The firmware I’m using can be found here. :)
I don’t find it any usable and just don’t use it at all 😅 I feel like there’s enough unused combo space left, no additional keys needed :)
