Example Input: I was very excited when I received this product. It was what I expected but I was greatly surprised how much I could fit in the bag. I was using it for my children's clothes on a flight to Florida on spirit airlines so it was the perfect size. My only complaint is that after one use the seams are ripping on 2 out of 3 bags we used, And that there is no longer handle on the bag.
Example Output: 3

Example Input: Most of the buttons worked when these were new, but never the one that pairs to your device. I was able to get them to pair by starting my music, and using the settings on my phone. Since I bought them last minute before a trip I just went with it. Now, a year later, none of the buttons work. The sound quality and noise cancelling were very nice, but now the volume is stuck at a level only audible in a quiet room... Not really where you need noise cancelling.
Example Output: 2

Example Input: The story idea was good and so is the author's writing style, but for me there were too many things that didn't add up. Riley is supposed to be excellent as a profiler, but I didn't really view her insights as extraordinary. In fact, sometimes she's rather dim-witted, as evidenced by one of the later scenes in the book with the female patient. Most of the action seemed to be a frantic race from one place to another, where the minor characters ended up doing more of the rescuing or discoveries than the main characters. I didn't feel a lot of investment in the romance between Riley and Thayne either. Maybe it's because the reader doesn't get to see their attraction for each other from the beginning of their relationship.
