Example Input: It was easy to use yes. But it didn't hardly give any color. The color I had was very spotty! It took using over half of the bottle to even start to notice anything.
Example Output: 1

Example Input: I like the pages and the layout. The problem is if you have to carry it around much the outside cover deteriorates quickly. After just a week or so mine is coming off.
Example Output: 2

Example Input: This think looks and feels nice out of the box. But the clamp needs to be more heavy duty. The bottom part where the tightening crank is bends way too easily as you tighten it.
Example Output:
