Just mixed this up, great shake and vape, the blueberry doesnt come through very strong, mainly because the TPA watermelon is a flavor that takes over most other flavors at least in my experience. Blueberry wild usually takes at least an hour to come through when mixed with strong flavors. I will try the 10ml sample I made in another hour. If the blueberry wont shine through, I may add a percent or two of blueberry extra.
