As a new guy, I hate to go against the flow, but...
When I first heard about e-cigs, it was on the radio... One of my favorite radio personalities was cancelled in NYC and I was listening via a computer stream from a radio station in Alaska, and there was this commercial for a cigarette that plugs into your USB port! I knew i should be cutting down, but I didn't want to go for the chemical lobotomy, so this was for me. THAT was a scam, the package never came and I had to charge it back on my credit card. Then some time after I was accustomed to smoking these things and had one good brand, i decided to try a free trial to, well, try out the competition. I paid $7 in shipping for a battery, two cartridges, and a charger. It was a really long lasting battery and the cartridges tasted more like tobacco than what passes for tobacco these days. Needless to say, the refills were hideously expensive. I called to cancel after the first shipment, and they said, okay, we'll cut the price in half. They still aren't cheap, but they are also much cheaper than the $12 a pack cigarettes here, so now i have a monthly "treat" from my regular brands. Not a nightmare, not a scam. And since my regular main brand is from China, I have a ready fall back in case the FDA makes good on its threats to stop shipments at the airport.
