I have noticed over the last week or so I have been using cartomizers that life of each carto seems to be heavily dependant of what kind of juice I use in them. My favorite of all Atomic Cinacide tends to foul the carto in 4 or 5 refills, or 2ish days where the USA Mix usually takes 4 to 5 days to see the bad taste/bad performance come out. Does anyone else have this same experience or am I doing something wrong? I did attempt to clean the cartos after a few uses but it seems to me they get a nice warn wet dog taste to them so I now just toss them when the performace issues arise.
