Um, FWIW, I agree with Atty. This is a risky business and those poor vendors get a lot of defective products from China. If you return a dud, they send it back to the manufacturer but it's a hassle and their profit margins are probably very small. If they were to issue a refund every time they get something sent back to them, they probably wouldn't stay in business very long. Nature of the beast. Not to mention dishonest buyers who are always out there, unfortunately; many of them like to try new gear and then return it if they don't like it. Sad but true. We have a couple of ECF friends who work now for e-cig vendors and they confirm that people try to return everything, including opened e-juice bottles, simply because they don't like them or come up with some story that the item they got is defective when it really is not--usually user error or they just don't care for it. Just ask Lorikay...
So,
@Katmar take your store credit or replacement and be grateful that they are being so accommodating. That's really the best they can do.

You'll have to shell out 200 bucks, but you get a lifetime warranty.
