Hey Big D... I have 10 of these things now that I'll trade ya.
Everyone had micro fractures straight out of the box. Only one of them has been tossed due to leaking but then again, I've only used 3 so far.
LOL, IDK vapspaz. May be just my old eyesight. I did manage to find 2 tiny fractures in two off them.
Considering we're still using the original four (re-wicked), that are approaching two months old, I'm unconcerned. Really don't think I'll have to buy anymore for the remainder of the year. Though if they come out with a version with drop in coils I'd likely get some of those.
I doubt these in their current configuration could be made with a different plastic. The design relies on rigidity. Hey, maybe a $20 version. Pyrex tank with replaceable coils and a choice of stainless, delrin, or ceramic mouthpieces? Hell I'd but some.
