I'm looking at the SXK iteration as a "let's see what this is all about" since they have the dna 40 and a CHINO brand 70w box available. It is single 18650, comes with the Kanger and Aspire doodads and you can get the Exocet clone for $14.99
It will give you a feel for the size & shape for sure, which are extraordinary.
I can't speak to the rest of the stuff though as I've no experience.
