I think you've convinced me to try one, because I seem to have trouble with the autos I have. I get that hissing, too, as others have recently mentioned, and sometimes, after I've vaped a carto for a while, it seems that I'm getting liquid in my mouth from them. These are all prefilled cartos, so it's not something I did filling them. I first got that liquid feeling from RY4, and just today from 555. It's as if a little liquid gets on my lip, and it's slightly irritating and sweet/sticky. Maybe this wouldn't happen with a manual?
But Im wondering what I'm doing wrong to get this kind of problem. I asked about it a while ago and tried whatever advice I got, but it's the same. I just vape anyway, but I still go to my analogs for satisfaction, and maybe this is partly why.
