So ive got a couple newish 510 attys. After about 3 days they started hitting GREAT. Then they dwindled down some. I did Highpings cleaning method, and they seem to work better. My problem is when i take a drag it feels as if im getting mostly air not vapor. Its like sucking on a pipe that has a carb, and not pluging the carb.. if ya know what i mean anyone else experience this? im using a 3.7volt nicostick by the way
