Example Input: Of the few Hot Cocoa flavors we've tried, this is the best so far.  It has the richest flavor and I dont notice the artificial taste that others have commented on.  Its also very affordable compared to other k-cups right now.  I thought that the k-cup making process must have gotten more expensive over the last year, but now I know they are truely sticking it to us since these are still reasonable priced.
Example Output: 4

Example Input: Love this brand. Great price with save and subscribe. My husband loves them. Top with whipped cream in a can and I have a happy man. I wish you could buy all pepermint cocoa.
Example Output: 5

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:
