Input: Consider Input: Thought I would try this shampoo due to the attractive pricing, a lot cheaper than the Bumble and Bumble purple shampoo I was replacing it with. This shampoo did not clean my hair very well. My hair always felt greasy even after repeated shampooing. Going back to my tried and true Bumble and Bumble purple shampoo.

Output: 2

Input: Consider Input: Had high hope on these. Think that it's such an awesome idea. However when you put it in use, it's kind of flimsy. Unless you have pure soil you can dig, if there are any rocks, roots, wood chip... Good luck to your fingers.

Output: 1

Input: Consider Input: I really like the layout of this planner, I've automatically bought it every year for the past 3 or 4 years. But this year, the spiral ring is smaller and the pages don't lay flat. I've only been using it for a few weeks and all the pages are already ripped due to the back and forth flipping of planning my family's schedules. I've tried loosening the ring but that only made the back pages come out. Very annoying.
