This upline bubblers diffusion is fantastic, it’s built like a tank and has a huge hit. (amazing for the size and typical Grav quality) Cleaning this bubbler is not bad, just don’t wait till it’s really dirty. Very nice with a vapexhale attached!
This is definitely up there in my all-time favorite bongs. I cherish this and I have yet to find someone who doesn't agree that it's the nicest hitting bubbler of its size that they've used.
A bubler that fits in your hand like a water jug, but is glass throughout and gives massive rips that won;t leave you hacking up a lung. Amazingly smooth.
My absolute favorite bubbler. The 9 inches of smoke purifying really makes all the difference.
I was looking for a bong with a straightforward design to mix in with my "scientific" bongs and this was what I decided on. Boy, am I glad I did. I get nice hits off of it regularly and it works just as nicely as many of my fancier pieces.
