Example Input: This is the microwave version of the original. I cannot stand it. The noodles have no flavor at all; and to me it is not spicy. I will not order any more of this product!
Example Output: 1

Example Input: I had high hopes for the convenience of this product.  My daughter LOVES hot chocolate. This really was a total disappointment.  I threw these kcups out.  If you use the smallest setting on your Keurig, you get 3 oz of watery hot chocolate.  Larger settings are not drinkable.  Save your money and get cocoa packets or a good tin of hot cocoa - and take advantage of the instant hot water the keurig provides.
Example Output: 1

Example Input: We have been purchasing this product for several months and have enjoyed it in the past, but this order is inferior.  Did the company change hands or outsource their production?
