Example Input: Another excellent book by this author. It's not morbid or icky-just states the facts. Great for young readers (I wouldn't go below 13 though, just because it's not ...oh...easy to read? Not because of subject matter, but because it is written in an adult voice...she doesn't dumb it down.) I am planning to buy several more for Christmas gifts.
Example Output: 5

Example Input: How simple is this product?!!! Is like a pair of socks. Slips over the window frame easily. Allows me to roll the window down fully and give the dog an impression of a barrier. This has helped me so much with air circulation for my dog should I leave him in the car. I recommend this product!
Example Output: 5

Example Input: It didn't make it a year. Not sure if the sun broke down the material or what, but it tore by the strap after a couple month. Then we had some wind and they cover tore right in half. Ugh
