i wasn't sure i was going to like ecigs, so i ordered the No.7 disposable kind. anyone tried it? i'm getting very low levels of vapor and almost no nic hit, even though there's quite a bit of throat feel and i've using the high level carts. the battery seems to be going fast, too even though i've only gotten through 2 of the 5 carts. am i doing something wrong or is this just how disposibles go? it leaves me afraid to shell out the cash for a recharable full featured model.
