I also have the pen but can't imagine why a new battery would be flashing. Do you have another battery to try? If another works right and that one flashes, you might have a bad batt. Contact Steve....he'll do right by you.
Are you using a new atomizer? They have that horrid factory prime that more or less has to be smoked
through. I hate it myself but put some drops of
juice on it and keep puffing away and it should burn off. That's the only thing I can think of that would make it taste like glue.
There's a lot of ways to clean an atomizer; some people just wash them out with hot water, some use vinegar, some use Everclear liquor, some boil the, etc. Also, you can "blow them out" first.
There is a whole
thread around here about cleaning them. Just make sure you put some more liquid drops on it after washing it to moisten it again.
Hope that helped. But don't be afraid to contact Steve if your stuff is new. He's easy to work with.
