Very tempted myself also! Freakin' ingenious simplicity at it's best, design-wise imho

Your build above, which wouldn't be able to work good on 3.7'ish v(under-load), I imagine would absolutely shine at those volts this puts out and with great surface area and max dense'ness! That is probably the exact build I would run myself if gotten it, lol!

I have read about possibly blocking the airflow with your hand/fingers and getting hot-
juice on hands if overdripped, but I don't think that should be an issue with propper usage honestly...
I just got two smpl's, one SS with magnets and copper-pin, and a copper c-clip style, which after short stress-testings(20g dual macros at 0.12), doesn't show signs of hot buttons yet!
I yesterday got a king v2, which has the most awesome threads and build-quality! Unfortunately it was pre-assembled with the 18350 tube on, and I couldn't get it off, plus the atty 510 adjustment pin was stuck + lock ring also stuck open! After a good freezer resting, I got everything open except locking-ring, but that's OK as I don't lock recessed button mechs, but I would still prefer to get it open for cleaning threads. The button is really nice feeling and it's for sure a great mod which i'm definitely very fond of, infact i'm using it right now! THANK YOU ninja!

(EDIT: After extensive usage, no hot button at 0.12 ohms and nice medium stiff stock spring. DAMN fine mod this is! Sturdy, beefy tank of a mod, lol, but oh so nice... Highly recommended and shocking 12 bucks only at FT!)
A good cleaning trick btw, which you guys of course already know, is dumping the disassembled mod into a vinegar and salt bath for two minutes and then afterwards rinse with hot water(+ sand the contacts with some rubber or pencil-eraser, just to make completely sure, and use a toothbrush on threads/everything). The acetic acid of vinegar(like citric acid of citrus-
juice) dissolves oxidation and salt fastens the operation time highly. Much faster than polishing everything fully up with polish-cremes. Well, maybe the later is more thorough, but vinegar/salt bath is really a fast cleaning method for sure, when feeling particularly lazy...
Now i'm just waiting on an abaddon and an extra of my beloved nikita's, plus more velocities + springs, and I will take a little break and fully get to learn everything...
The castigador I just got is so tight on the springs for the battery, that it's a hassle and I really hope they will loosen in time...
Sorry for ramblings...
