Example Input: This playing mat is awesome!!! It is thick to provide enough cushion. No funny odors. easy to wipe clean, which I love! It is foldable, so save some space and I don't worry about my cat running on it and scratching.
Example Output: 5

Example Input: I don't usually read too often but, decided to start reading from a list of top 10 books for leaders. I saw this in a TED talk and just had to read it. I am about half way through and Simon's insights are very useful.
Example Output: 4

Example Input: Received the old version of this "new and improved" shusher. I specifically bought this to get the version in grey that has raised buttons and a twist off bottom for ease in changing batteries and I received another one just like the one I had before. Very very misleading. Not happy at all. Now I have to take time out of my day and return an item that I thought was something else. i would order again but fear the same thing would happen.
