The pen tastes good, haven't used for very long so still determining the effects. I do have to say, when I received my pen it had leaked. I let them know and they were in contact with me immediately to make things right. Hard to find that anymore these days.
I bought this to help me on my long drive for vacation since I can't drink energy drinks... they were a lifesaver for me! Even the people I was with preferred these over their energy drinks! The flavor is perfect and the hit is smooth. I will definitely keep purchasing these!
Great for a quick pick-me-up, one puff is strong enough for me, the Gush flavor isn't bad, has a cheery flavor to it.
