I recently picked up a QB-001 from Sunshine Store to accompany my cherry E-Nano. $18+$23 shipping, single honeycomb. This piece is everything I wanted it to be. Sturdy, 5mm thick glass, 19mm sidecar, perfect size, no drag, little diffusion. I had reservations about getting any of the pieces that seemed ostensibly better or cheaper because they had far too much diffusion for my tastes. This tube has the least chug of any bong I've used for combusting or otherwise. I can get fat, milky hits with relatively little effort and hold them as long as I am able.
I've been using warm water mostly, though the piece uses such a small amount of water that it cools pretty quickly. I haven't had a chance to pick up any distilled water or cranberry extract, so some hard water stains have started to build. A little lemon juice will remove those, right?

I also had no need for the oil rig parts, so I asked for a bowl with a handle on it instead. SSS included two of that bowl instead of the oil rig. Unfortunately, I'll probably never use them, but it's nice that the seller was communicative and willing to make a substitution like this. All in all, I couldn't be happier. A simple water pipe solves every problem I've ever had with vaping. No more tickly throat, no more unfathomable dry mouth, just beautifully conditioned and tasty vapor.
While the piece is a little large, I don't feel too bad about transporting it. It travels pretty well wrapped in some bubble wrap. Since there are no moving pieces or complex percs and everything is at least 5mm thick it can safely be slipped into a duffel. This piece is so nice, in fact, that I'm contemplating investing in a separate, smaller travel-piece. Does anyone have any suggestions? I'm looking for something that goes with an E-Nano and/or a Lotus.
