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.............
Example Output: 1

Example Input: I had high hopes for this product when I first opened the package because the noodles had a great texture and the sauce looked appealing.  The food was easy to prepare at my workplace.  However to me, the taste was very oily and flavorless.  I'm a big peanut satay fan and was expected more spice in the flavor.
Example Output:
