These two are my favorites of all. Sky has a light fresh, cool flavor that isn’t overpowering but simply flavorful. Vibe is peachy. Just like a peach pie. It’s a wonderful light fruit essence. Since I’ve been buying Waterdrop I have lots of energy. My head isn’t tired. I’m focus and ready for whatever life throws at me. There’s a few issues I’ve had. It’s really hard for me to bend, open and peel the microdrink cubes. And when your bottle sits on the table for a time it tastes and smells like heavy vitamins. Don’t get me wrong. I love the way the vitamins make me feel. It seems that when water is cold the flavors overpower the vitamins. Just an observation. Leslie
