Example Input: This is the second one I buy, I really like the color and the look of it. The only complaint is that it is slightly crooked. It is not completely straight, but it holds my movies and cds good. The other thing is that the adjuster moves very easily and sometimes the movies fall. Other than that a pretty good product.
Example Output: 4

Example Input: Was not sent the correct item. Don't want to have to hassle with a return. The item I received is good quality, however it does not change colors like stated in the description. Disappointed.
Example Output: 2

Example Input: Didn't really work for any of the issues my dog was going through. I feel like it was overpriced and didn't last that long. I won't be purchasing again.
Example Output:
