Vaped at 60W on 0.18 ohms, holy cow this stuff is sweet!!! Might drop the Bubblegum to 4% next time and I'm not sure if it actually needs sweetener or not. I dont have Bilberry or Double Apple so made my own Grape trinity with CAP Blueberry and CAP Fuji Apple. Give me a yell if you mix it up, would love to hear feedback. Part of my adventure for a good Grape vape without having to try a million different concentrates.
