well could be just a nasty flavor, for me high PG mixes taste like crap, try a different flavor. Are those the prefilled caros or blank cartos? That's an cigalike style isn't it? Flavors are hit and miss unfortunately. Prefilled are much more expensive then buy
juice in bottles and filling your own tanks, blanks or cartos. It's unfortunate that you didn't find this site before buying your gear, so that you'd have a better understanding before purchasing. Check out all that's available here and educate yourself about what vapping is all about. At the minimum, would recommend trying to find a local smoke or vape shop that carries vape gear, find a tank or blank carto that will fit your battery and sample some flavors to find one that you like. If you have nothing local, then find a vendor online that has small sample packs that you can try. Lots of options are available. Good luck and welcome to the forum
Vape long and Prosper.!!
