Example Input: Work well and made solidly.  For whatever reason the Keurig takes longer to complete the brewing cycle when using these cups and the liquid bleeds through the filter on the outside of the cup making a small mess.  They do the job as intended but could use a different type of filter to make the experience less messy.
Example Output: 3

Example Input: We love Trader Joe's Just the Clusters Vanilla Almond Granola Cereal but were very disappointed with the quantity we recived for the price charged.  As a result, we returned same.
Example Output: 1

Example Input: Seriously this product was as tasteless as they come. There are much better tasting products out there but at 100 calories its better than a special k bar or cookie snack pack. You just have to season it or combine it with something else to share the flavor.
Example Output:
