I got mine in a couple of days ago but haven't tried it yet. I noticed also that the stem doesn't sit flush.It is also very tight,couldn't get it out. May have to stick it in the freezer for a while. Noticed also that the stem is hard to hold when I ain't wearing my dentures-- and I don't wear them around the house. May have to make a different stem.A little beeswax on the tenon of the mouthpiece before you start smoking it will make it easier to remove the bit when you want to. The draft hole in the chamber is very small, so it might plug up on you. It can easily be cleared with a piece of wire.
