It seems there is two version of clone around, other one has that beauty adapter and MTL deck, the YFTK version does not. Both are on 3fvape.
That tank fitting could be the biggest weakness on the YFTK, it has not fallen off by accident yet but surely it should be a tighter fit. I can turn mine from the drip tip easily, and the tip is not tightly fitted at all.
I have the tank in my pocket for work now so lets see how it stays on...
I must also say this tank wicks like a champ and vapor production and flavor are both very good. Hard to say how different the vape is with the MTL deck, but I can live with this one.
