Re: Question for you hookah heads
QT's are not as good as a KM, let's just make that clear. That being said, for the size and money, they are probably the best or close to it. In my limited experience with my girl's QT, the draw is a bit more limited, it doesn't manage the smoke's heat as well (short stem), and the purge is not that great because of the chamber design. The tray is also somewhat annoyingly small, but that is to be expected.
That being said, for a fairly cheap, small hookah, it definitely has an air of solidity about it.
