Example Input: Is does not have an actual screen protector built in like i thought it would so that's disappointing, i had to add one underneath, the case was a bit stiff and hard to put on but overall its good im not mad at it. This was a gift for my sister and she really likes it
Example Output: 4

Example Input: It doesn't fit exactly how the picture shows. I guess it might look different on some faces, but when I wear mine the skull from the top jaw looks decent, but the teeth are stretched out across my face. That's all you see is the teeth stretched out. It just a bit off like your wearing white paint.
Example Output: 2

Example Input: I bought this as a travel mirror, as hotels don't always have an idea setup for make-up application. It helped quite a bit for this purpose. The fact that it doesn't require removable batteries is a huge plus, as you'll never wind up with dead batteries. (As long as you have it charged, OR, you're near an outlet or laptop that will recharge it via USB.) The angle of the mirror is fixed, which is the only slight problem, depending on the height or angle you need. Otherwise, a nice convenience for travel.
Example Output:
