Hey all, I have tried to find an answer to this, but nobody seems to have this problem. I am trying to use my GotVapes Hybrid Fuse Multi Use 510 Atomizer on my Zmax, but when I do, the draw is way to tight. It is only tight when on the device because the air holes are getting buried in the threads. It doesn't happen with my cisco spec attys because the air holes are right up against the bottom of the atty, but with these hybrids, the air holes are ever so slightly lower. Any help would be awesome because they seem to vape really well, just to tight. I have also tried it on a 510 to 510 adapter without the center hole, same thing happens.
