Mine arrived today. It left Shenzhen on the 1st. So you should get it sooner rather than later.
Been using it for the last couple hours. Works as well as the Kangxin flask, but does seem to have a more noticeable firing delay in Kanthal mode.
Finish is mostly excellent looking, mine came with a hair thin, not-too-deep 1" diagonal scratch to the right of the up/down buttons, nothing I can't live with. I suspect Kate sent me a demo model, and I don't mind that at all. Does make me wish they had the silver in stock, or rather, I was patient enough to wait for the silver.
Now, while the finish LOOKS a lot nicer than the Kangxin flask, I have to say I still prefer the satin finish on the Kangxin for actual use. More grip, it isn't a fingerprint magnet, and the anodizing is thicker and should wear better. Oh well, life is a series of trade-offs.
Buttons are much much better on the Waidea, no comparison. Better feel, better size, countersunk holes.
Battery caps appear to be a harder grade of brass, and polished nicer than the Kangxin, but I had hella crunchy
threads on one tube that took a fair amount of cleaning to sort out.
510 connector just works, just be sure to snug it down good. Nothing I own quite bottoms out, and I like that, it saves the finish on the top but is close enough that I have to hold it up to the light to see the gap on most attys.
Threads are nice on the 510 as well, feels as good as my Varitube equipped
devices in that regard. And no more fighting with that blasted adjustment screw on the Kangxin.
And Bloke? Mine has no problem at all just knowing it's a Kanthal or Ni200 build, I don't have to change modes.
One difference in the display is when you take an atty off the Kangxin, it shows -.-- for the resistance, with the Waidea, it shows 0.00. Everything else seems exactly the same, right down to how it flashes when going into temp settings, how it round-robins from 1w to 40w if you press the down button again, and how the damn thing always adds 0.1w to your power setting when you try to lock power. I'm positive at this point that it's just a slightly newer revision of the board in the Kangxin.
So far, IMHO this is still the one to get folks.
