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: Maybe these a better when they're very fresh.  You could ruin dental work if not careful chewing these.  They taste great.
Example Output: 3

Example Input: THESE TREATS ARE MORE FOR A LARGER DOG AS THEY ARE VERY HARD AND THICK.  THE GIRLS (my maltese) LIKE THEM EXCEPT WAY TOO BIG AND HARD TO CHEW FOR THEM..
