I trust in Zach.
I'm new to vaping, actually just about a week now, and I have been buying bottles like the supply worldwide is going to run out from vendors all over.
I've got Vapor 4 Life, Vapor Zone, NaberJuice, Carpe Diem, and Keystone Vapor sitting on my table but I'm finding that the only real good juices are from home brew local small outfits like Keystone and Carpe Diem. Good good flavor with no 'strange' manufacturing taste to them like wholesale outfits.
Zach from Keystone is a wounded vet, makes a GREAT product, and has me for life. He is my go to guy for juice already. That's all I can say.
