Then you need to check your reviews. I have this exact zen atty clone which I recieved with my caravela clone from vaportek and although its not stainless steel and the glass can be a little fragile....
HOWEVER, it builds extremely well and vapes fantastic. It handles sub ohm coils remarkably well especially with flat kanthal builds and 500 mesh. The vapor and flavor are better than an agat2 and the wick hole is nice and tight to the positive post so there are no hot leg issues.
Im thinking your build may be out of whack therefore so would your review, not that Ive seen it. At $15 the atty above is well priced and works great.
Is this a hybrid, no. All the versions of this on fasttech are the same exact thing as the first caravela clone. The colored ones just have the zen atty fused to the top of the tube instead of a top cap.
I refuse to buy another clone. I'm glad that they are there to offer people a cost effective solution, but not for me. I have spent too much on garbage clones just to chunk them in the trash. Everything I buy now is named and well reviewed.
