I got the first-gen JC sample pack about a year ago, and there were some flavors I loved! and others that weren't my favorites....
never had an atty die from these juices, I even mix PS juices with JC juices when I drip/dip, and haven't seen anything bad happen to any of my atomizers.
I'm a fruity-flavor vape guy, so I LOVE JC's peach cobbler, and i enjoy mixing their sweet strawberry and wild cherry juices. The tennessee cured and the other tobaccos were alright, but I gave them to a friend who recently started dripping after using pre-filled carts only. I sold off the strange flavors I got, such as chocolate almond decadence(smells yummy) and hawaian kona coffee(smells yucky). LOL
My opinions are on the juices I got last spring, and I know they've changed their formulas so I might order some of the new peach and give it a shot.
