The Sloppy Hippo dual pipe is awesome! It is a fun, practical, graceful and affordable design that also makes a nice gift. It definitely gives a little extra umph with each hit, and it’s incredibly smooth. Made out of thick, colored borosilicate glass, it is a nice  piece to share with a friend, where each person has their own bowl to smoke or one person can light up twice. It is perfect for taking a dab and smoking a bowl at the same time. There is a standard water chamber in the bottom bowl and a second one above, which allows the smoke to circulate and cool some more, before entering the tube. For anyone who has always wanted the double water pipe, this thing does the trick! Well made, ridiculously easy to clean, & just a really cool, useful, fun piece!
