All great advice, thank you SliM! I would have to agree that this is most likely just a 'small batch' issue, and isn't/shouldn't be a common thing. Especially looking at a picture like this, you can tell that it should or can hold a lot more weight than the standard mouthpiece (which doesn't weigh much at all) (the mouthpiece that came with my GBD bubbler weighs 52.5 grams, or 1.85 ounces) Vs. the weight of the HT (much more ) Either way, I don't plan on leaving the mouthpiece in my replacement piece, when I receive it. I never have felt comfortable leaving accessories/attachments in my pieces, when not in use. Even if weight isn't an issue, the potential for damaging more than one piece, is greater when you have things attached, than when separated; If you tip over a piece, with a male/male adapter/glass nail/dome all attached, you'll probably lose a couple things...However, the piece, or parts of it, might survive if it were 'disassembled.'
