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: This is the same exact blade that came with my Ego electric mower. I'm still using the first blade, but BOY does it get dull quickly. I have to keep resharpening with a file. This is the exact same size, but they should have used harder, better steel to make the blade. For this price, it should stay sharp longer. Once you own their product, they KNOW you have to buy their blade. \ Not satisfied. If it were half this price, I would have given it more stars. TOO expensive for what you get.
Example Output: 2

Example Input: The shipping was fast but the phone was not in good condition as the seller stated it had scratches and it stated that it didn't have any scuffs of scratches.
