Ex Input:
This tea was supposed to be loose tea.  I purchase loose tea all the time.  Instead of packaging the tea in bags, they left it loose.  Gave a very couldy tea with a bitter taste.

Ex Input:
Several of the seller's listings indicate 20% Kona blend.....but the delivered product does NOT have this package printing. As a long-time Kona coffee drinker, the contents are more indicative of 10% (or less) Kona coffee. Have ordered twice....and completely disappointed.

I highly recommend these very tasty Kavli Thin Crispbreads. I wanted something different than just white bread for sandwiches. I hate whole wheat. I love rye. I saw these, noticed the ingredients couldn't get much simpler and gave them a try. Topped with cheese, or a sandwich spread or whatever you'd like they're very tasty. I feel as full after 2 or 3 of these, topped of course, as I did with just white bread. They're nice and thin so it isn't like biting into anything hard - just a nice crunch. The flavor isn't strong at all - it is very mild and nothing like a rye bread you might have purchased in the past. Then I noticed that they are only 20 calories per slice. What's not to love? They taste good, they're whole grain, they're super low in calories, it's no crunchier than a potato chip, and I feel satisfied while chewing and after eating them. Oh - and they keep forever in the cupboard. I definitely will be buying these for a long time. :)
