Example Input: I bought this because it was listed as one of the top five "cutest" kittens. I have to say, when i got it, it's an okay kitten. He is very attractive though. Unfortunately, although he is fairly soft, he's not that cuddley. This little guy definitely takes some effort to make him lay flat. He's pretty heavy considering his size.
Example Output: Bad review

Example Input: This lamp does work. A little tricky on installation, but...works. Unfortunately it's not as bright as you would hope. Not a terrible light.
Example Output: Bad review

Example Input: Excellent sound and ease to setup. We put the subwoofer in a large room that has vaulted ceilings so this helps fill it with excellent sound. This system is quite small although it packs some punch. My favorite feature of the design is that two inputs are controlled by remote. I like being able to separate our speakers because we have one on each side along with both TV components (Sharp Aquos lcd TV) which only uses surround sound.
Example Output:
Good Review
