i think a lot of it is the finishing of the edges of the tanks... they are not as was discussed a while ago. mine which hasnt had any issues has small chips on the edges which can be microscopic cracks. i believe zen is working with the manufacturer to have them flame polished which would most likely solve a lot of the cracking issues
Yeah, I think you are right on that... A flame polish would have increased their strength dramatically, but could also wreck the tolerances at the edge making them impossible to install.



No, not waffles or pancakes (mmm, pancakes). Someone guessed it. It's a lipstick/nailpolish/makeup brush/whatever holder. Acrylic I believe. I got it from The Container Store. They have many things there that would work as PV/juice/vaping stuff holders.
