Almost great
Well the first one arrived broken, but the route coverage was worth it and I got a free replacement. It's pretty good, but there is one glaring error: the inner glass tube needs some kind of coating to prevent it from knocking into the outer tube. That is in fact why the first one broke during shipment, the inner tube cracked the end off of the outer tube. Maybe the silicone joiner needs to extend further into the outer tube? Maybe add a ring in the middle? I'm rambling but you get the point. Otherwise it's a great alternative to blunts, wraps, etc. Hits like a champ obviously since this review is quite long winded.
