Looks good!
It appears to be significantly smaller than the Jetbeam RRT-3 and thrunite TN30 and also has a considerably narrower handle than the Nitecore TM11 which will make it more comfortable to hold for long periods of time. I like the simple implementation of the single button UI (unlike the TM11).
I prefer the smooth bezel shown in post #1 to the crenelated one on the sample that turboBB was sent so hopefully it will ship with that or there will be an option at least.
I don't like the built in charging system though. It looks as though it might be easy to short and there's certainly no cell balancing going on. I'd probably remove the cells to charge.
