For an oil piece you want minimal diffusion. I have a DG fritted disc right now (probably the most diffusion you can get) and it's horrible for dabbing. There is a) noticeably more oil condensation and b) noticeably less effect compared to the same size dab taken on a piece with lower diffusion. I recieved the DG in trade for my mobius matrix, which I felt was a better dab piece. I've dabbed out some small pieces that are super harsh and some that are very smooth. The hit smoothness also has a lot to do oil quality and nail temperature. Small pieces w/ low diffusion help tremendously with flavor though.
So I had to agree on this (I owned 2 DG's) as it was obvious the same size dab would give me less vape exhale compared to my other pieces & yes there was more reclaim in the internal of the fritter. So though on one hand the extreme diffusion of the DG's made any dab non harsh ever, on the other it had those "efficiency" cons!
I sold the can and kept the glowing micro as the porosity was bigger on that one...
THEN I received a
Dab Essentials Domeless Nail and with all these channels it FUCKING TURNED MY WORLD UPSIDE DOWN, meaning my DG has now the exact same vape exhales as my other pieces/same effect, and clearly LESS claim then before both in the fritter & the can internal walls!
So thx to my new nail, my DG is back on my dabbing pieces podium!
Now back to the topic, I HIGLY recommend for a daily dabbing piece, with FLAVORFUL but SMOOTH hits:
BatesxWorm Diffusion Pump Bubbler
I own one and love it for everything: size, functionality, ergonomics, looks, easiness to clean...HOME RUN!
