"This is a very smooth product. It takes some practice especially when you are not sure what is suppose to happen. Once this pipe reaches the right temp, it gets the job done. My lungs felt so much better that I had to go back to the old method because I thought I was doing it wrong. All I can say is vaporizing saves the lungs, and this is a very different way to enjoy herbs :-) I wonder how the glass one is + If your gonna buy one of these, Id go with a wood colors not one of the painted models, I went with purple but the wood versions look more elegant, but either way, very cool product" - Shawn from Fla
