Hi Hal, I've been out of the loop for awhile. I love their Zen
juice. I will say that I haven't had to buy
juice in a year since I DIY. Before they came out with Zen, I used to mix BKK with Matterhorn. My last order with them I thought the menthol was too strong compared with their previous batches. I let it steep for several months and added BKK to tone it down. Perhaps my taste buds changed in reference to this juice but I still love and vape their juices when I get tired of my own LOL.
