So some background. I've been using Dawns juices for some time now. I've gone through 20ml of Banana Cream, Clearly Grape and many others. This time I got some Jingle Bell Cookie, sorry to say but this juice will ruin your atty/carto. I'm getting huge buildup of carbon after only one fill of my boge 510 cartos. This doesn't happen with any other juice "So far". Juice taste great but it's ruining my cartos to fast to keep vaping it.
