Example Input: I purchased this as a present but it doesn't come As shown in the picture.  It is little white bags with the flavor written on them.  Someone receiving it as a gift wouldn't even know what it was unless I explained it to them. Will be returning.
Example Output: 2

Example Input: The coffee pods are convenient but the quality of the coffee is not good (you will find this especially if you are used to using a grinder, fresh beans etc). I'm not sure if this is due to the pod itself or the machine in terms of temperature, pressure. I suspect the problem lies with the pod technology and the coffee within. I'm going back to a grinder, fresh beans and a traditional machine.
Example Output: 2

Example Input: Next time I will order only the original flavor.  The other flavors did not suit me.  Too much of an aftertaste.
Example Output:
