Must have
This piece is a must have. So much smoother with it, and it's awesome to watch the smoke swirl around. Also makes it easier to see how much you're getting. Highly recommend! Thanks Grav!
United StatesEven Smoother
The addition of this pre-mix chamber to my recycler has made a very smooth experience even smoother. This is fun science enjoy the little tornado! I highly recommend one of these.
United StatesBetter than expected.
It works so well that I dont need to use ice in a percolator bong. Only drawback is the bottom of device at the neck is fairly fragile. I just tapped the coffee table picking up bong & it broke off. I want 2 buy a new one but it was a gift & I need to figure out way to reinforce neck.
Broke after 3 days :[
The ground glass male end broke into pieces after a few days of use. :[ Is there any sort of warranty? I was Happy when it did work.
