Example Input: The story is interesting and I did buy several, hoping the next one would be longer than a chapter's length. Sorry but 30 minutes read time is not even a novella and I have read short story's that were longer.
Example Output: 1

Example Input: All of the leggings I have ever purchased have always been one size fits all/most, but these are the first ones that I've ever had trouble with. The ones I received were not very stretchy, especially in the waistband. They also had a very strong smell that lingered after the first wash. I guess they are fine for the price, but I would not buy them again.
Example Output: 3

Example Input: Good headset for one month but the cord splitter broke and now it's unusable. It was not from normal wear and tear - the piece just came off. I don't even know how to get a replacement piece.
Example Output:
