Example Input: We received a box of these at work and the whole package was gone moments after opening it up!  Great biscuits and now I am ordering a couple boxes for a few gifts for people I can't figure out what to get...
Example Output: 5

Example Input: Tastes good, but barely any protein. If you want protein, get Nutiva's unflavored 50% protein powder. You can flavor it yourself. It's cheaper and has more protein.
Example Output: 3

Example Input: Since a DOP product is not readily available at my local grocery stores, I got really excited when I saw the photo of this product at the Amazon website because the photo states that this product is "D.O.P. Certified."  But when I received the shipment, it was a huge disappointment.  It was a different product than what the photo promised.  (I can buy the one that was delivered to me at my local grocery stores very easily.)  Very disappointing.............
