I am extremely impressed with the 10 Calorie Vitamin water. I would say I am more concerned than the normal person with health and I try to completely avoid artifical sweeteners. The XXX Triple Anti-oxidant (red) drink is my favorite. I just wish it was available in larger quantities so I wasn't buying so many plastic bottles. I'm not that interested in getting my daily vitamins from it, just looking for a tasty drink when I'm tired of water.
