Have you guys heard of these? (of course you have). I'd like to believe in them, but it seems like bullshit/too good to be true. Are they an actual viable/more healthy/much, much less costly alternative to real cigarettes? I'd like to believe they're the real deal (for my benefit), but they come off as quite gimmicky.

(also, it can't be good to suck on a battery all day right?)
