Works great except that the air volume is too much before the smoke reaches me. I should have gotten the 8”. That’s what I’ll do but I’ll have to wait because I just can’t spend that kind of money for two bongs.
I love this high quality piece because with it's "geometric" ice catcher, and it's smallish beaker build, I can actually smoke from this bong. The larger ones I don't have the lung capacity to clear it, but This GRAV is a reasonable, quality, well thought out bong. Highly recommended for chronic tobacco smokers and pure stoners alike.
My son told me to buy a simple beaker-base bong, percolated down-stem, decent bowl. This Grav glass 12" bong with ice trap, gives the smoothest, richest hits of any bong I've ever owned. (Careful! Sneaky. Big hits!) And the sturdy glass parts are easy to clean WELL! A little heftier bowl would be even better!
