I really like this piece. It's short, so that the vapor doesn't travel too far. The mouthpiece has a small opening, making it great for tasting whatever you put through it. It has really nice diffusion thanks to the super slit puck and swiss design. The recycling function works beautifully, you can see the bubbles go up through diffusion and back down the drain. One thing that I didn't like about this piece is that the mouthpiece is too close to the 14mm joint, making me scared of my concentrates boiling over and hitting my nose. With that being said, you can add a drop down and the problem would be solved, the base is so big you can slap the thing really hard and it won't tip over. I wouldn't recommend doing that to a $400 piece though. :) Great product!
