If the flavor is muted or dry, try removing a piece of wick at a time until you get it right (vape it for a while before removing more wick). I had to remove a few pieces of wick from my EVOD to get the flavor I wanted. You can also flip the gasket that sits right above the wick. If it starts gurgling, you are leaking and have taken it too far so you simply need to put a peice of wick back or flip the gasket back.
The EVOD is amazing after a bit of tinkering (compares with dripping), but I use 70% VG/30% distilled water.
I tried that and i am either getting odor or a drop or two on my battery connection. One or the other. The odor is most likely coming from the silicone cap that is making contact with the top wick. I think i may just have to live with the leaks. It is not a lot and hopefully my battery can withstand it.
