I discovered this at the supermarket last night.
Not bad. Doesn't taste bloody at all. (Sango refers to the blood orange flavoring that has been added.) I think it's only available in Europe right now, though I doubt it will be released in America. (Somehow, I don't see a fruit with the word "blood" in the name becoming popular any time soon.)
Too bad, though--it's pretty good stuff. I like it much better than the Diet Coke with Lemon. (I am pretty sure they got their lemon flavoring from Pledge.)
