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: My cats won't touch the stuff. They know better than me. Oh well, back to their nasty little pellets, which they gobble down. Thanks for nothing. :-(
Example Output: Bad review

Example Input: It's an attractive product but the design is very bad with regard to heat loss. The handles can only be positioned in one position so hot air rises on all three sides. It does look good and it is easy to use. Just doesn't warm anywhere near what you would expect unless it's a totally cold room. I've had no problems heating clothes or other items that are placed under it. I am using this unit right at my front door where it get lots of traffic.
Example Output:
Good Review
