I bought this one $16.59 Kayfun Lite Styled Rebuildable Atomizer (4.5ml) - clear tank section / matte surface at FastTech - Worldwide Free Shipping after doing tons and tons of research on all the models FT offers.
Seems the discussions forum pinned this model as superb with top notch machining and most of the comments mentioned it was the best clone they have received when compared to the other FT clones they have .
Super smooth threading with a seamless fit , airflow works flawlessly and i have had zero leaks , easy to fill with an o ring equipped fill screw and hits like a beast on the MVP with builds in the 1.2-1.8 ohm range.
After playing with many different size and types of coils i strongly prefer micro coils on 28 gauge Kanthal and a mandrel no larger than 1/16th and then lightly compacted and wicked with cotton.
I have noticed (with 28 gauge) anything larger in diameter than 1/16 to wrap with does not heat the coils fast enough because the MVP has that cutoff feature
For $16.00 you can't go wrong
Lol!! Sorry, but I'm just not buying it...
