Yeah I have some trouble with mine not wicking very well, I like having the screw in the fill hole though so I don't always have to keep the thing upright. With the fill hole screwed up, I can leave mind lying down and it doesn't leak.
That is my only reason OF putting th screw in. But lack of flavor weighs more so screw is back out. My Travels have one DID and a couple of phiniac tanks. Home has all DIDs and the phiniacs. Each device has different flavor. Phiniacs have flavors that I never vape in my DID. Never. Two reasons. Either they don't taste well in DID, or I don't WANT to know how they are better in DID.
