Ok, like lots of people, I had my doubts about this kind of thing, but now I've first hand experience, I see it's problematic.
Here's a pic of a Clear smok Tech 1.5 Ohm Dual Coil XL Cartomizer - (so not a cheapy one...)
This cart was filled 3 weeks ago, and I've topped it up 2-3 times. As you can see, the bottom part of the tube, where it meets the connector is cracked. (it's now actually loose) It's not a "be careful with the carts" issue - it's been stood on my desk doing not a lot. I take care of my bits
What's your thoughts?
