All is perfect accept one thing.
I love this setup, and plan to get more STAX pieces. My only problem is the large, female ground joint on the base piece is not round. Any, mid-section or mouthpiece put into it wobbles and has a bit of an air leak. Looking closely I can see 2 points that are causing the problem. I might have noticed it if i wasn't so excited to test it out after it was received....so no way to return.
The perfect hit
This bong is amazing. If you get the right amount of water, you get a hit so smooth it feels like you smoked in air. Everyone who smokes this is so impressed. Highly recommended.
