I remember someone was asking about the durability of the glass not too long ago. I have never had any problems, up until now. I just got back from class and sat right on my AIWB... I wasn't looking and had left it sitting on my video-rocker type chair so it must have been along the curve when I broke it. I have sat on it before and it's been fine. I think it's just because it was being supported on both ends and not the middle. So it was like karate chopping through a board, with the board being my AIWB and instead of a hand I used my butt. Poor AIWB never stood a chance.
The funny thing about this is that it also ties in with the combustion talk. A few days ago I actually ordered a replacement AIWB because my buddy really did a number on this one. It's still fine, just very dark on the bottom. We've used it before, but he doesn't have the technique down. It sucks that I just broke my AIWB, but it's funny that I already had another one on its way in the mail. Don't get me wrong, in my experience it takes a lot to break the glass. This just happened to be set up in such a way where it broke. So I guess I'll just do a temporary fix until I get my replacement in a few days. If I still had some tubing I'd just hook it up to water.
Edit: I found some of the stock tubing, which I know some are not fans of, but I don't mind it. I still have the whip adapter, but I sold my bubbler so I'm using a whip setup to my HTs. The glass stem is wider inside (looks like thinner glass) so I have to pack different and it seems to take a bit more to heat up, but I'm honing in on my sweet spot again. I forgot how much I love this vape.
