I've had mine for about 2 months now. I like it better than my Ergodox, but it's not perfect (yet). Maybe I need to train muscle memory more still, but I'm looking forward to the extra modules shipping for having extra thumb keys. Furthermore I'm still annoyed at the arrow keys needing a modifier, where the Ergodox has an extra row of keys for that. Hardware build quality is impeccable, software/firmware is only just getting there though. Programmability is better (well, easier) than w Ergodox, although I imagine that by now there are graphical tools for that; back when I configured mine, I had to hack the C firmware to get it to do what I wanted.
