I like the taste, but the dropper isn't effective.
As other reviewers have said, this tastes just like cough syrup, which I happen to like.  I can't really know if the vitamins are making a difference with my health, but I certainly haven't seen negative effects.  Any vitamin is good, especially B vitamins.  My only complaint is the dropper does not effective suck up the liquid all the way, nor does it squeeze into my mouth very easily.  I usually do two half droppers and make it work.  Not a big deal, though, and still worth 5 stars.
