Ok so I am less than one week into vaping and bought a kit that included prefilled menthol cartridges. I got the modern vapor lux pv. I LOVED the pre filled carts so I decided to try the halo mentol ice juice with double coil cartomizers. I filled one using the "condom method" (I hope I am using the right term). I vaped and it SUCKED! I mean really. I like a lots of menthol minty flavor and this only has a bit of mintiness in the finish. The start of the vape is kind of medicine like or chemical like. I thought I was just doing something wrong so I put a few drops in my prefilled and though it was better it still had the same taste. I am thinking that I might have to buy a pure menthol juice to mix with the one I have. I know that I am in a learning curve so any suggestions would be most welcome. I would especially love to hear from any folks who like a minty menthol flavor. PLEASE HELP. Finally, with my carto, how will I know if I have filled it improperly? You guys ROCK for helping me.
