Example Input: If you love super dark, rich, bold and thick flavored coffee then this is the coffee for you...with one problem.  Personally I love coffee that embodies everything I just said.  I love esspresso and the like.  To find a K-cup that is this bold even on the 10 oz. setting is great...but there is that problem again...  It smells, tastes, and leaves the after taste of burnt urine!  Like someone torched a public restroom and mopped the floor with coffee, then packaged it. Yum!  There are other dark, bold k-cups out there that have a better smell, flavor and does not have a nasty after taste. You may not believe me, and that is fine, but get a sample pack before going for the 24, you'll thank me later. Try the Green Mountain Coffee Extra Bold Sumatran Reserve K-Cups. Better all around cup of coffee.

Example Input: My family is gluten intolerant and we use this product extensively.  Pancakes, biscuits, waffles, it doesn't really matter what you need to bake, this mix comes through.  This is my go to mix above Bob's and all others we have tried.  Try a box, follow the instructions for pancakes, and tell me they aren't awesome... go ahead... I dare you.

Example Input: Pretty good product.  The taste isn't the best but it's definitely not the worse either.  It gives a pretty smooth energetic kick.
