I've got to admit that I'm not a big fan of adding flavor to my water. I don't even add lemon to my water so adding a powdery mix wasn't something I was super excited to try.
However, Mike LOVES adding flavor to this water and he's in love with this stuff. His favorite was the Berry Medley Warmers.
I tried both and if I had to drink one, I would choose the Strawberry-Kiwi. It tasted like the powder dissolved better in the cold water even though you would think it would be the opposite.
