Quite possibly the worst thing I have ever drank. I was sucked in because of the sale but at any price it's not worth it. I bought the grapefruit flavor and it was like drinking flat sparkling water, no carbonation and no flavor. I normally like diet drinks and sparkling waters but this was terrible. I showed up at my sister in laws with an 8 pack and she didn't even want to try one. She said she bought a different flavor once before and also hated them. I wish I could return them but we opened two. I recommend staying away from this one at any price for any flavor.
