As a background, I am not that new to DIY, but not that experienced... but as you all know every new RDA/RDTA needs an experimental introduction. This 16mm RDA was a trial. I couldn't go to my standard 'goto'builds such as 3mm ID 26/38 gauge kanthal or stainless Claptons that I use in everything from Aromamizers, goblins, Ijoys, velocitys and recently the one 'authentic RDA' I'm glad I purchased, a 22mm Goon, partnered up with a therion 75 DNA BF Mod. I had to think back to the murky pasts of 'long gone into storage thing's such as my beloved Russian 91%'s and Kayfun lites.
This line of thinking didn't point me in the right direction: I built without too much trouble two little 28 gauge 2.5mm ID coils, together 0.9 Ohms, at 3.7v around 15 Watts (I'm trying to build to mech mod fixed voltage, as I'm expecting a couple of Coppervape BF mods soon). This configuration was distinctly disappointing. I put the RDA down, and started on another BF RDA I received in the FT order.......(SXK IAI V2 Styled RDA Rebuildable Dripping Atomizer V2, 22mm, SS, Silver (SXK) / SKU: 6548000)

Further pondering overnight pointed me along a new direction: 'Put as much under the bonnet as you can'
So: two little 28/35 gauge Claptons (2.5 mm ID) were wound, and thinking along the lines as 'BIG is Better' I shoehorned them in: 5 or 6 wraps coming out at 0.66 Ohms, pulling 20 plus watts at 3.7 volts. By the way, the holes on the build deck more than happy with these Claptons..

PERFECTION: This little RDA steams effortlessly along on full air flow...
Built pulling this much power in such a small chamber, the resulting flavour and cloud production belies it's looks. OK, I've changed the driptip to another standard fasttech staple, (Stainless Steel Round Mouth Drip Tips for 510 / ViVi Nova / DCT Type K, 24.7mm, 5-Pack / SKU: 1437403), but apart from that no changes.
Pros compared to our standard 'BIG, fashinable RDAs'
1.... Volume of vapour, even though much reduced coil surface area, the RDA allows the same nic levels to be used compared to bigger builds (I was concerned I would have to spike the stock Heisenberg with a small amount of nic to compensate)
2. 20 Watts or 40 plus? Iv'e been mooching around with an aromamizer supreme as my daytime and a Goon 22 as my stay at home, running at 30 to 45 watts The big problem is Battery life on 1 cell Mods. 20 watts will last all day on one decent 18650. This is a big consideration
3. Build quality. Spot on. Looks like it will last well. The machine tolerances are very close, make sure you align the top very well to the body when you put back together otherwise is tends to jam...this is not a negative point)It makes me wonder what the authentic is like, if this is so good. I can't find anywhere in the UK I can buy one. (If I find a great clone, I try my very best to buy an authentic if I can, just to support the R and D and hard work these guys do)
4. SQUONK . SIMPLY BRILLIANT. a good 7 or 8 puffs a squonk. Easy to take driptip off and see whats going on until you reach the 'point you know how much to squeeze' Squonk pin with a very nice large diameter hole in BF pin makes for easy use with 70% VG. I thought this would maybe be too small for a good squonker, but it functions better than my Goon, and more puffs per squonk.
5. I cant get any leaks/weeps as long as I ensure I have a couple of vapes after squonking, something I haven't achieved you with a RDA in my pocket.
6. FLAVOUR...... have to say others beat it, but it's pretty good. Probably the best all rounder I've found to date/

Cons: I really cant think of one (except I have to try to source an authentic, and a another of these from fasttech), as long as you enjoy the challenge. It is really great to see something so different and enjoyable. It is a truly all day RDA with very few negative points.

This little guy works great. It does take a bit to build it but once I got the hang of it all is good. I started it off on a Dripbox and so far it has worked great. You do have to pump and fill it every few drags but I am getting use to it. I really love how they have the BF pin flush with the bottom of the deck. It has helped me from over dripping.
The top is a bit loose so picking it up with the drip tip is not a grand idea. Most of the time it stays on but I have had it come off in my hand when I had slid it in my pocket.
I did notice the metal where the drip tip goes in was pretty sharp. I took a bit of sand paper and smoothed it up.
All in all it is a great little tank. I am loving the intense flavor I am getting.

Dimensioni ridotte,ghiera dell'aria regolabile esteticamente molto bello.La rigenerazione una volta presa un po' di manualita' risulta abbastanza facile.Arriva con un drip tip troppo largo l'ho sostituito con uno piu' piccolo da tiro di guancia.Il mio e' arrivato con l'o-ring della base troppo lento tanto che il top cap si sfilava facilmente,ho risolto con questi o-ring:https://www.fasttech.com/products/2156304 ,adesso e' perfetto.

veramente un ottimo atomizzatore, riesco a sentire ogni singolo ingrediente del mio aroma. ariosità e possibilità di scelta dei fori veramente comoda. unico contro il pin bf in acciaio che è molato male, graffia il pin della box, se avete manualità si risolve con poco. il pin chiuso invere in ottone è veramente ben fatto. da comprare assolutamente!!! materiali e livello costruttivo fuori dal comune!!!

ce petit dripper si vous ne le connaissez pas est juste parfait
des saveurs à tomber par terre (pour peu que le jus soit bon lol)

This one of those attys I think every squonker should buy. It gives good flavor and looks awesome. This clone is well built as well. I own 4 of these to tell you how much I enjoy this product. Will recommend 10/10

Un très bon dripper bf, tout petit, bien usiné et sans défauts!
un peut compliquer à monter.

I was resistant when I got this, I hated building on the origen v3 but this new 2 post design is pretty good. the post holes are not the biggest so don't expect to fit dual claptons.

très bon usinage.
le pin bf vient avec.

Pas déçu de mon achat. Un rapport qualité prix très intéressant. Il est vraiment minuscule. Mais monté sur une box bottom feeder avec un réservoir de 10 ml, il assure, il a un rendu des saveurs exceptionnel! Bon c'est pas un dripper pour faire des montages de fous en quadcoils, mais il n'y en a pas besoin.
