I don't care for it much, but my kids do. I only bought it because my oldest son was telling my dd she was crazy, that they didn't make such a thing, so when I saw it in the store I had to bring a bottle home.....shame on me!
I prefer the orange MD that they introduced last summer. They also have a "Baja Blue" MD only available at Taco Bell. That tastes like carbonated kool-aid to me but again, the kids like it.
