Example Output: 3

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: Really liked how easy this case is to put together. With the glass screen protector its 360 coverage. The downside is this glass protector. Its not full adhesion. Its only double sided tape around the edges. I really got it centered and it seems to be holding fine for now. Its a great deal for full coverage and the case alone is worth the price. Update: 11 17 18 The case is good untill you remove a few times then it WILL break at the tabs that hold it together! If your planning to nvr to remove this case then it should last awhile.
Example Output:
4
