these have external ego threading, I used one as a 510 extension, making use of the female 510's air grooves for my cartomizer. Had six, not five, in the bag unopened, probably a miscount...threading is good enough, definitely not high grade metal here, but should do the trick for the price...many potential uses, get creative! Have hole all the way through, could be used for air activated mods and potentially squonking (my next project)...thanks to FT for stocking this old stuff...

This is another great squonk rda that will be gone forever soon...I loved mine, but the paint on Vapeasy's black painted version had no adhesion, resulting in the top cap being an ugly mess. The vape is great with this atty, regardless of looks, but now I have a faultless, flawless 9.00 rda that looks great, too! (and I can retire my black one) It's nothing new or particularly special, just a solid, good-looking single coil rda, built for slim claptons or Aliens, and squonking. Those who like their coil legs to be parallel will be happy with this build deck...there's no posts on opposite sides of the deck, just a block, separated by PEI as an insulator, with two small threaded holes and grub screws. The deck is smartly designed to keep leg "leftovers" from shorting your set-up when the cap is installed, and there's plenty of airflow- similar wide open to Haku or Wick'D rdas. Less than a ten spot? Mandatory squonker purchase! It never leaks, and flavor is incredible, though totally expected from an atty like this. SO glad I finally got a Stainless one...now I will use the Daywon much more frequently. Don't sleep on this bargain, it will be gone soon!

Nice job by "new" manufacturer 5AVape. Everything seems spot-on, a perfect reproduction. Everything fits, seamless and snug. O-ring tolerance is perfect...nice and snappy, cap "pops" into place, and is very satisfying. Dual air inlets on each side allow a good restricted vape fully open, and will please MTL types when shut down incrementally. ..The coiling area and larger screws beg for a larger coil, and my first build is loud and proud at .16 on a mosfet squonk, and this thing can handle it, no problem. Fully open, the Aston has enough air to keep my cap cool, though I'm no "chain vaper". The vape is very similar to another recent RDA, the Haku Duet. Both hold big coils and have similar air flow, and have diminutive stature. The Aston wins in simplicity, with a tried and true design that offer trouble free, long-time use. 5AVape did everything right here, and the price is quite fair for the level of quality on display...again, the finish and laser work is perfect. Nice Job on a great squonk atty.

the three negatives listed above are all valid and should be taken into consideration...this is not an rta for those wanting long uninterrupted vape time. Wicking must be thinned and allowed to "breathe" when poked into the smallish wick holes and out the bottom, almost rdta style. Full on DL users will need to alter their style, as this is restricted, even wide open. The airflow is genius, though future iterations could benefit by a "marking" system, to let users know where their preferred airflow ring orientation was. The under coil airflow is 61 tiny holes, amazing how precise this rta has been built and designed. Packaging is nice, with coils and cotton, atty stand and sunglass bag/ wiping cloth. This RTA is any easy build, medium difficulty wicking and medium to high performance/ flavor atty. Many will love the industrial look, many will love the machining, and many will love the vape it gives....overall, not a bad purchase at all --THC makes quality products, and this one is a winner.

Just like all the others, but brighter and more lively, and NOT black. All parts and pieces are perfect replicas of the highly popular and original AIO, with SXK adding Escribe capability, along with a 200.00 price cut - I'd call that enough reason to buy, but if you need more prodding, know that SXK makes replicas of all the best bridges, too - and they perform better than ever, with a style to fit any vaper. Check these out - every hardcore vaper needs one!
