Smokea Downstem

Good fit and quality. Would prefer closed end so ash would break up or trap in downstem.

Glass downstream diffuser

This version is more robust than the first one I had,, and It has larger holes at bottom.. Both very good. The rig needs cleaning daily, but no problem with various 4:20 products. As always, customer service was excellent...great support and very quick delivery.
