Yup, it sure does screw together (and can completely disassemble it also, easily). So if you're worried it's like a Heron that is only held together by o-rings, that's not the case with the Prom.That Prometey screws together, right? Got a link?
Not sure if you mean my clone's link or the original modder? So here's both...
Original: Atomizer «PROMETEY»
My Yeahsmo clone's vendor on Bonanza.com: http://www.bonanza.com/listings/Prometey-V2-Titanium-Mods-Atomizer-RBA-RDA-Dual-Mod-CLONE/292089963. He seems to use individual item listings instead of one listing offering multiple quantities. So you may need to search vapor2flavor's Bonanza booth for Prometey in case the one in that link has already been sold. Borislav (the vendor's name) also answers questions pretty darn quickly, and ships real fast too. Both my Proms arrived in just a few days from FL to AZ.
If you want, I'd be happy to strip one of my Yeahsmo Prometeys down completely for you, and provide pics. (ooh, more Prometey Porn? )
FYI, I think I mentioned in my original post about this clone that the ONLY issue was a little left over metal shaving over deck air hole on one, and "below deck" airholes on "stem" on the other. Both easily shaved off with a metal nail file, no dremel or anything else required.
