Thank you for your service.
Cignot is a great choice. Terri is wonderful and will help you day or night.
Like Bare, I also was a menthol smoker, and detest most of the 'menthol' juice I've tried. I started with Cignot and love love their EcoFresh Pure, for when I want something light. I also have found that I love their English Toffee. For some reason I am craving (and I'm not talking lightly, but like PREGNANT craving) anything that has caramel or toffee, or the like. I also liked Cignot's Staypuff ok.
For batteries, the PCC (as other's said) is a must for the 510, it can charge one battery while you are using the other one. I also found a multi charger to be quite handy. The five one does me fine. Stock up on some extra attys, batteries, juice, (and you can easily find good deals on 'extras' in the classifieds.)
If you PM me your addy, I'd love to send you some juice. I went a little overboard this month

and have plenty to spare! I'll send some extra carts too.
As to "what will people say"... you will get over that soon. I started off with a "real" looking cig (white, red tip, blah blah) and found that smokers wanted to try it and non-smokers didn't have a clue. Now that I've switched to the 801, it looks like a pen, and no one gives me a second look. I'm home most of the time anyhoo, so the few times I'm out and about, I never get a comment. I even wear it hanging around my neck in a Leyford Lanyard. Looks like a pen!
HTH!
