After ready reviews on double chocolate and steep times I was apprehensive on trying it out. What an amazing flavor it is. I give it 4.5 out of 5. I mixed a 50 50 mix and tried it after 3 dates steep. Good vape after 3 days. After 7 days even better. I am sorry I have not vaped it by its self but have mixed it with whipped cream or espresso. I have some peanut butter from FA arriving this week and look forward to mixing both. Hope this review is helpful to others as it is the first review I have ever posted.. I mixed at 12%.
