I am in love! I ordered the Sour Watermelon chiller alongside some Boba Tea and I am so happy I did! I love the flavor! I make myself a shaker full with ice and pop it into my car with me on the way to Mom duties and it keeps me hydrated and refreshed. The taste is not super sour (ie puckerworthy) but it's just enough punch to wake you up! Not too overly sweet either. I absolutely love this flavor and will be getting more!
