I just bought some of these at Vapercon and I like them a lot Push button 510 Cartridge
I like these too. still prefer direct dripping, but they are good for driving and stuff. Cags- I tried those jessies again, and they worked fine on a 901 atty, but just can't get it to work on my 510. weird.
as far as regular carts- the fill kind of dulls the flavor for me so I don't use them
my hub still uses carts on his 901. but he does not read here and know about all the neat .... to try! and I can't tell him too much because I am a closet vaper- LOL
