Example Input: I have been looking for a low price smart watch, and I finally found one. It not only tracks fitness, and heart rate, but it notifies me when I have a call or text. Something that not all of the fitness watches do..
Example Output: 5

Example Input: The bag was good to look at but unfortunately, it stank. I tried saddle soap, several different internet cures, leaving outside in the cold for several days. Nothing worked. It still smelled like rotting meat. It's out in the garage. I wanted to return it, but the seller is in another country so returning it is more expensive than just throwing it away.
Example Output: 1

Example Input: I received this order right before leaving for a long camping trip. It was missing the plug to close it. I contacted amazon. They could not help me with getting the missing piece, so I tried to contact the seller. They never responded to me.
