Hi @paehtod ...I appreciate your tip and I will get some of those screens and try them. Believe me, I try to clean these screens but in practice material gets on the other side of the screen and there is no way to clean it. No way to burn it off either. The screen is critical to function of the vape. I'd like to see them use a small thin metal ring to serve as a stop and foundation for the screen and have the diameter of the hole in the wood block better match the screen diameter. Those two minor tweaks would make it much easier to change screens. I am a believer in the basic design of the OG! It is very hard to beat...
