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.

Ex Output:
Bad review

Ex Input:
If you love your dogs this is the perfect thing to give them! My husband likes to keep on eye it so he will be eating his breakfast in bed now! The only downside for me was that I wish they came with a way of securing them more securely. So far I'm still using it, but have had trouble keeping them together!

Ex Output:
Good Review

Ex Input:
We expected more from this shower curtain set than we received. It looks okay, just not what I expected. Probably wouldn't buy another.
