The propellor perc and the recycling design really makes the hits clean. I can't remember a piece that had nicer hits.
At first it looks like someone made a bong out of a glass beer stein (which is pretty cool). Once this baby starts filling up with smoke you knwo it was made by a true expert, and the hits are as smooth as they come!
We got this as the first new piece to use i our new place when my girlfriend and I moved in together. It's been proudly displayed on our coffee table almost every day since (except when our parents come over), and we still use it all the time. Great hitter.
