Edge2O: Caffeine Charged Water

Edge2O is just what you think: caffeinated water. You can't taste the caffeine, so we are merely reviewing this product on the basis of the water quality. It's pretty decent stuff. The water is not amazing, but it's not horrible either. So, it might be worth a try if you need the extra edge.... The one thing that we really like, however, was the nice little sports cap. It allows you to quickly open and close the beverage without losing the cap.
