Okay...so I'm the new guy here. Not to the world though. I'm a retired Aerospace Design Engineer (30 years). One thing I'm seeing in the is E-Cig biz I don't like is the same bashing in many other production venues. This ones better that that one and so on. I've got 10 mods, 2 digi's and now doing the rebuild's (including factory atty's), 2 rda's and 2 RTA's (no such thing as RBA Rebuildable is one word) Either it has a tank or not.....period. In reference to the Title of this post. The quality of the product is directly related to the skill of the mechanist. Regardless of what Country he's in. I have good and bad from either side of the ocean. Clone or not. With everyone's honest input we can weed out the bad and all is good.
I've also discovered in my hording of mechanical junk after 30 years, I came across about 2000 yards of 28 gauge s.s. wire on spool. Wrap on 3mm wood stick (old VCR cleaning Q-Tips) 6 wound coil build and burn-in touching the leads to a 9 volt batter (no torch need that way). 2 seconds is all it takes. Wood is non-conductive. It just burns off and you have a perfect coil left at .7 ohms. I wick with organic cotton. After about 3, 3ml tanks I just drip some Isopropyle Alcohol and scrub with a toothbrush and good as new. Anyhow...howdy from the new guy in Dallas Texas.

. We had a saying when doing aircraft interior components. You can't really polish a turd,,,,but you can roll it in glitter.
