Good but please beef up the descriptions

Downstem was perfect as advertised, though I think it would be helpful to add to the description with info like the metal basket inside is removable (a plus for my app), the max and min inside and outside diameters, and the material thickness of the cap.

works perfect, very happy with downstem

Perfect fit!

I bought this item because I had somehow lost the one that came with my water pipe...and it works perfectly! I had to get a different color since the one I needed was sold out, but I don't mind that as long as the stem does its job. Shipping was also faster than expected.
