I've got one of these on all of my glass that requires a downstem. That includes bubblers, bongs, and ash catchers. They are the best downstems I have ever owned. They are better than stock every time. Always better airflow and efficiency. Quite impressive and would recommend to anybody. They are way better than tree-diffused downstems.

Great!!!

Love this new downstem. It flows really well, the joint is high quality, the slits are polished well and the name looks really good. Not too much diffusion but a good happy medium I think.
