Thanks for the welcome, everyone! The question I had was about Tasty Vapor's batteries, but I've decided to order from a different vendor anyway.
BTW I tallied up last night, and figured out I've spent about $175 on my e-cig and juice/parts so far, and that's still $400 less than I would've spent on analogs in the same time. I'm so glad I found the e-cig!
