I've tried this in 3 flavours. Orange, grape and watermelon. Orange is my favourite. Grape is okay, a little too strong. Watermelon is horrible!
It's a great energy boost and overall not a bad product, however, I do wish the flavours were "natural". The taste is a little too fake, more like candy, and not something I would consider overly healthy. But for the meantime, I'm happy with it till I finish the product.
