Really nice project. We definitely need more wireless split options that are shaped to fit the hands. I only wish it had hot-swap switches or a non low profile option.
A non-low-profile keyboard would need to be designed differently, to avoid the keys colliding (due to the curving). It's probably not feasible as an option, that would be an entirely new design.

That makes sense.
