We never received this item. It was shipped one way, then sent via carrier pigeon. Very disappointed! Did not bother returning.

Bad review

Ex Input:
I have purchased this product before and it tasted fine, however, the last two times, something was not quite right. And sure enough, my third container also left an awful metallic taste behind it. I gave one bottle to a friend who had similar problems, then decided that we should throw them out. That is what I did. Too bad because they are good tasting.
