Crash, you're a man after my own heart. When i saw that necklace invention, i thought the same thing. Everyone would think you were the biggest dork that ever lived. Now don't get me wrong, the necklace invention would be great for heavy vapers to wear around the house. But not to a bar where you are trying to meet people. I literally LOL when i saw your reply.
You can try using that necklace invention in your pocket. Like the ecig would go in your pocket in a discrete soft holder and the holder would be attached to your pocket. Nobody would even see it down on your hip. Kinda like in the 90's when a lot of men wore wallets attached to a chain and the chain would hang outside your pocket. But instead of a big chain, you'd use a very think black lanyard.
Anyway, now that i've offered up advice you weren't looking for, i would say GO FOR IT. Buy some disposables and let us know what happens. I've been curious about the disposables too. They can't be that much more than analogs really, when i was paying anywhere from $6.50-8/pack.
p.s. I love it when you curse in your videos. Very natural way about you.
