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

Got the book as a birthday present. Very dissapointed that it's only 40 pages. I thought it was around 150 pages and way overpriced. There are better books on the market. If you can't find a well reviewed one pass this one. I'm trying to return for refund. Really feel scammed. Thanks Amazon. :/

Bad review

This is a solid coffee pot no doubt about it and makes great coffee. It keeps the beverages VERY hot throughout my day. The only drawback for this product that I have found are 3 small holes in the bottom of the carafe to let in air. Even with those caveats, it's still an outstanding product.

Ex Output:

Good Review
