if they aren't boge, i dont do them.
there is tons of hype around joye attys and i would assume that would be the same with cartos.
there hasn't been one bad boge carto i have ever owned. i haven't even ever popped a coil in one yet including the time my button was stuck and burnt the paper off the outside, the thing still works.. not that it taste good now that its pretty much burnt everything inside
my advice, if it aint boge, dont use it.
