That looks exactly like the first flask I got with the paint or coating on it. Same box, logo on box, font everything. I Can't speak about the board inside, as I never used it (it was kindly and graciously sold to me broken for retrofit purposes).
I'll say this... And it's only my opinion. I think the waidea from focal has a superior feel and finish for about $10 usd more, and that is only my personal opinion. Ymmv.
The finish may be better, but the chip in the SXK is a whole different ball game. It's slightly tarnished by the low resistance reading, but that can be handled (and hopefully will be fixed in future revisions.)
Spring loaded 510; up to 60W; C temps; Coefficient of Resistance adjustment to use non-Ni200 wires better (or at all) and to do more accurate TC adjusting for atty static resistance; no delay from sleep; working lock; down to 0.06Ω (once the low resistance is fixed)
I can't comment on the black (yet - I may know by next week) and maybe there's more of a finish difference there but the finish on my silver is lovely, really nice feel to it. Good buttons too.
Most significantly, I don't think I've used my Waidea once since I got this. Can't be bothered worrying if an atty is going to be a pain screwing down without the spring 510, so when not using the SXK flask I use the ipv4 or one of my new Kangxin Mini VFs which have the Rayn chip at 50W with spring loaded pin and a flashlight; single battery.
I enjoyed my Waidea, it was a good third mod. But I'd never buy another now. If the SXK black finish turns out to be bad I'd just limit myself to silver.
