As good as protein drinks get
I personally find all protein drinks somewhat unpalatable.  That said, this one is acceptable for my two daily doses.  I mix it with Crystal Light lemonade and that takes some of the cloying sweetness away.  No empty calories from sugars, which is nice, and it mixes up almost as well as it claims to.  I should give it a five, as it is superlative for its class of product, but protein drinks really just don't inspire that level of love from me.
