I received a free sample of the tropical mango Gatorade Hydration Booster. I decided to use it while cooling down from an at home work out. It tasted really good, better than I expected actually. It wasn't grainy and it dissolved completely. I felt very hydrated and recharged. I really like that it comes in compact, travel friendly pouches so on days where I go to an actual gym, I can pack a few without it taking up too much space.
