It appears there are two threads, so I'll just repeat my comment knowing one will probably get deleted.
I think it's great. Reduces travel distance between mouse and most used keys (alphabet cluster), like a 60%, and doesn't sacrifice the other dedicated keys. It's also still completely compatible with any default tenkeyless keyset.
If that thing has the same build quality (and $100 price tag) of the KBT Oni, with the double sided PCB and all, along with the new thick cherry profile PBT keycaps, I'm completely sold.
Oh, and I also love the new sleeved cable.
