Arizer Solo / Air Replacement Glass Mouthpiece – Bent

Look the piece fits , except is feels loose an wobbly. You have to hold it very straight and prop it up otherwise it will wobble all around , it works but god damn why can’t you make it so it sits in without wobbling.

This is probably the best stem I have used, it’s a bit wobbly, but works great, the customer service here is great too.
