I like the idea of it & the basic design, but it does not let enough air flow to occur. It's tiny holes restrict air flow badly even on a good 18mm high air flow bong or bubbler it;s like trying to breath through a coffee stirrer. I would return it if I hadn't used it on a test run lol
Just 1 hit & I was DONE with this damn thing. It'll sit in a drawer with some other glass I don't like or use anymore or I'll give it away. Ant heating that thing..... without an E Nail it takes way to much time & fuel with a micro torch to bother with. I only gave it 2 start bc I like the basic idea of it & I like what it could be.
