@wall I have some side to side play with my medium wooden stem as well. Tried it in the Splinter too with the same result. Still seems to make enough contact inside the female joint that it seals properly and doesn’t affect vapor production.
Not sure if it’s designed to be removed but I was able to remove the glass insert prior to using it. But, now that I have a few packs through it I can’t remove it (not trying with a lot of force though).
Outside of the middling fitment I’m really digging the wooden stem. I like using the dosing capsules for a quick unload/reload and the a-maze cooler really does seem to help cool the vapor down a lot. I’m able to take comfortable rips at 405F, which typically leave me coughing with the 4” straight stems I have. I’d say it’s close to, if not on par with the vapor “coolness” I get when using the DDave Vapor Cooler stem dry. Love the look of it on the Tubo, too!
