Atomizer is pretty decent, I've had mine for about a week now. It does have a few issues, none of which are deal breakers, but it could have been done better by SXK. Deck is very nice, and quite build friendly, 26g is shown below, wicking is simple, and straightforward.
First, no AFC, it says it has one in all the adds I've seen for it, but it does not. A couple of ways that a workable AFC can be improvised. Simplest, and most basic is get a silicon band(vape band) and use it Aromamizer style. The second method, while it would not be as effective, would work, and allow some restriction without affecting appearance would be to source a longer 510 pin which could be turned into the decks af tube. I don't mind the Airflow as it comes, so I've not really bothered.
Second issue, this may be just specific to the one I received, but the double o-rings at the top of the tank were locked to the glass, glued? not sure how or why, but it simply would not come loose. I used it about a week before really trying to get it loose. End result, tank broke, no replacements offered anywhere as of this post.
The o-rings actually tore apart trying to get them off the glass, no way was mine going to come apart without breaking the glass.
Third issue, though not that bad, the deck positive block must be press fitted, and it is very tight, I tried putting a wrench to it, could not get the block to budge. This issue has been reported by the few others I've seen that already have one.
No solution for this issue, but it really isn't a problem, except if you want/need to break it down for repair or cleaning.
Airflow is good, but not as open as the slots, and 4mm bore under the coil would lead you to believe. The choke point is the small holes drilled in the Deck pin (visible through the base af slots as pictured). This also causes it to have a fairly loud intake on the air, not quite a whistle, but somewhat annoying anyway. One user drilled it to 2.5mm successfully for a more open airflow, and it also reduced the noise.
Flavor is good, about like a typical Kayfun opened up, better flavor atties aren't hard to come by, but for the price it is a winner.
As mentioned, no replacement tanks have been offered so far, the tank is 22mm OD, 19mm ID, 1.5mm walls, 33.10mm tall, glass is not overly strong, a drop or two, stubborn/glued o-rings like mine, it will end up broken.
I did look through a bunch of spare glass I have, sizing is pretty common, ID/OD is same as many tanks, Zephyrus, Subtank Mini, just to name a couple. Unfortunately the 33.10mm height is 3mm or so longer then most. Lemo tank is a fit, but about 7mm to long.
The closest I've found available for purchase without going custom cut is .4mm short.
Z Tall Tube That should work OK, and could probably take that .4mm off the bottom of the chamber if needed.
Hoping someone lists a cheap replacement soon, not my only tank so no rush for me.
