Example Input: I was initially very pleased with this product because of the flexibility in adjustments. Easy to install. My only issue with this product is that you could actually remove the angle mount from the wall with standard screwdrivers. Typically the only way you could remove a ring doorbell would be with the special screwdriver provided by ring.
Example Output: 4

Example Input: This hand exerciser is just what I needed since slightly injuring the muscles in my hand . Just by squeezing the metal coil I can feel it helping to flex that muscle. It's like instant therapy.
Example Output: 4

Example Input: This is more the first part of a book, establishing characters and motivations but lacking real substance. Clean prose (no major spelling or grammar errors) and well written dialogue. Depressing, since it only establishes the main character's situation. It's not bad, it's just not good. I will not be following this series. I prefer my novels to contain a full story. Even a novella should have more story than this did.
Example Output:
