Hi guys, i don't write review usually, but this one is a bit special
I got a "NextGen" from FT 2 weeks ago: https://www.fasttech.com/product/229...-tank-atomizer . It's a Infinite/SXK clone. GB has the other one (Yeahsmo), for 14 and 13 USD respectively.
The atty is gorgeous, very small for its 5ml capacity. I like the simple look, brushing finish, no logo. It has glass and brushed steel bottom tank sections. It comes with a 2 parts drip tip, i wish it were few mm taller.
But, the real beauty is inside. Basically, it's a pressure based feeder (like a Kayfun and extended family). Still, most people would say it's a genesis. Well, for me it's a real innovative design, from 3 sources: genesis for a top chamber, Kayfun for the leakproof design, and Inax for the center post. The result is a unique design.
The wicking: the intake from the tank is at the bottom through a pipe in the center with 2 small holes. The liquid is sucked up to the chamber when a puff is taken. The tube acts like the juice/wick channels in a KF, creating a porous "cork". It works, and really well! I think got 3 dry hits the first week, and none since (like anything, it works better once it knows its user ). Downside: it's mainly for SS mesh, because the wick has to wrap around the center post. As long as the mesh has been torched enough, it's simple and effective.
The chamber: it is a tiny cylinder of the diameter of the 510 drip tip and kinda float in the middle of the atty. It is held in place by the tube which sucks the juice, and 4 air paths. The geometry of the middle section of the tank made me think of one of my favorite destination, check this: http://upload.wikimedia.org/wikipedi...i%2C_India.jpg . That's a superb piece of machining.
Air flow: there are 4 options, you select basically which one of the 4 paths is used. There are actually pairs or vertical holes, targeted right at the coil. It's a bit on the restricted side for direct lung hits even in the widest setting. The AFC could have had more options, and allow 2, 3 or 4 air intakes, IMHO.
Build: the positive post has a threading for a nut, and a cut along that threading for pinching the wire. The wick is then sandwiched between the wire and the post. That's super easy when the atty is on a tube mod: just turn the mod 4 turns or so while holding the wire, the grab the wire under the screw on the base for the negative. Adjust the coil, pulse, adjust, done. It's simple and it works really well.
Refill: top filling, super easy. Sometimes it's a bit clumsy to unscrew the top cap alone. The solution is simple: the middle section must be screwed tight enough on the lower section. The o-ring is exposed then, be careful when putting the top cap back. You even have the choice between 2 kinds of o-rings: a black o-ring for a stiff AFC, or a red one for light action. Too bad, the red one on the clone is too thin and the AFC spins freely.
Leaks: 99% leakproof. It's absolutely a pocket friendly device.
Vapor: warm, very dense, intense flavor, tons of vapor given the restricted air flow, on par with the best RDAs. For me, it's that good.
My biggest grief: no fancy build. The coil is always vertical, and you cannot put "advanced" wires as it is. Maybe twisted 32 gauge is the best that can fit in, because of the size and the way the wire goes in the groove of the center post. I must find a way to put a clapton in there
Conclusion: my new favorite tank by a big margin, you probably understood already. For anyone who likes genesis attys (Kraken, Origen genesis, etc), it's superior in almost all ways. For the others: unless you want a huge air flow, give it a try, that's a completely different beast that works superbly.
