Example Input: These are great beanies. I have 2 and they are both pretty as well as functional. Very warm for daily walks. Not too big or small--a nice amount of slouch. Love them!!
Example Output: 5

Example Input: Love the lenses! My only issue is that with the telephoto lens, I can still see a dark circle around my photos no matter how much I try to center it. But can't complain too much. Lenses are great!
Example Output: 4

Example Input: It's been so long since I read this that I can't remember details about the normal things I mention in reviews. I only remember that I thoroughly enjoyed reading it. It was fun to see a non-magical person thrive in a magical world, and everything flowed together. Diverse characters were the cherry on top.
Example Output:
