Example Input: I love the way it looks, but it just doesn't protect anything in my backpack. It is too small and has sharp edges. I've had this for 2 months now and today I finally took off the top to wash it. The snap just flew apart and not a drop stayed inside of it, so I'm returning mine. A waste of money! :( bummer. I'd rather give $15 more on something that feels better... And also wouldn't you know it, I went ahead bought two more cases.
Example Output: Bad review

Example Input: This is one of the worst books I've ever looked at and read. It's just a waste of time. Save yourself 4 days with your friend (who isn't reading as well), read something, anything! You will actually learn more watching paint dry. In all seriousness.
Example Output: Bad review

Example Input: I bought this in February when we added 2 kittens to my household. I've had it for almost 4 months now and the kittens are still not using it. I'm not sure what they mean about being able to adjust the height. The lowest height was perfect for two kittens, but the highest is high enough that even one of them can't stand on. There's no way to lift these up easily to allow a cat to go on top, so they just don't like it.
Example Output:
