Tastes OK
Flavor is the first criteria I review when reviewing energy drinks, and I have reviewed a lot of them.  It's still too much on the sweet side but almost all of them are.  I don't know why they have to be so sweet, I usually add lime/lemon juice to them to cut the sweet.  That said, I play two hard sets of singles yesterday in the hot sun and had my water bottle filled with this energy booster.  I felt o.k. for the most part. Playing in the sun really saps my energy so knowing that I was still going pretty strong towards the end of the match tells me this stuff must be helping.
