This is my second purchase of the Grav Helix and this time around there are some design flaws: the base of the beaker has several grooves that keep it from being stable on a flat surface. There is also an unusual amount of resin that builds up around the mouth piece, which isn’t very pleasant. I never had this problem with the previous Beaker. I did notice the overall design of the bong changed a bit so I’m not sure what’s to blame. I will say though, that the “helix” of smoke produced while inhaling is a lot more visible. Always a satisfying sight.
