A couple things I've picked up on. Only fill the bowl about half way. Makes it easier to stir than when it's completely full. The whip that comes with it is pretty long. I went to the local Ace Hardware store and bought a shorter piece of tubing and used the extra elbow, the one for the bags, to make a second whip. Now I've got the shorter one for just the Mrs. and I, plus the longer one for when we have friends over. Also, vapor will escape when you're not drawing on it. I use the little glass tool as a stopper. I slide it into the end of the whip and it keeps the vapor from escaping. Take a series of short hits rather than a big draw. And watch the elbow while you're hitting it. You'll see the vapor in there. It's real easy to take too much with big hits and you end up caughing up a lung.
You're gonna love it. Enjoy!
