I got the X9 and the head it came with was DOA. Fortunately I ordered an EVOD 1.8 head which for the first few hours was great, but then I started getting gurgling issues and hot flavor.
I tried using the silicone grommet from the dead head and put it on top of the EVOD's grommet to try to make a tighter seal, I tried it upside down on top and regular ways. This seemed to make a better seal but still the liquid leaks
through.
Help!
