Ok so here's my newest addition. And fwiw I'm not really that impressed with it at all. .... I wish I could take it back and exchange it for a swing arm. Only the one they had though they were asking entirely way too much for.
Ayways, here are my gripes about it;
1) the mouth piece is a little too close to the bowl
2) The nail is glass and is too shallow IMVHO so it allows oil to spill over causing oil to spill over and run down the side.
(maybe just get the nail hotter?)
3) I'm getting some splash up in the mouth piece so i have to keep the water level Really low.
well that's unfortunate, I could put you in touch with one of the owners of the local head shop here who blows glass on the side. he fixed my Roor that was broken and I also have one of his sidecars he blew too. cool dude, does good work. if you got the change check out aqualabs that place is off the chain!
