Example Input: This is the worst book on personal finance that I have ever read. I would recommend this book to those with no economics background! Nothing new here. Buy Michael Lewis' books instead. The advice given by Mr. Kiyosaki are similar in nature but much superior.
Example Output: Bad review

Example Input: It was a good idea, but when you finally get it to work, then you discover that this piece of junk won't work at all, and is very hard to find any support for it. Do not buy this, the price seems too low, but I guess your gonna have a lot more problems than if you paid more. It's a shame...I'll never do business with NetGear again. Their tech Support only has 24 hours a day support. No matter how many times they're polite, they don't know much.
Example Output: Bad review

Example Input: I was so looking forward to getting this...I did my research and this seemed like a great product for us. We followed the directions carefully. The first thing we got after turning it on is an extremely strong odor--like what you would get if you sprinkled cinnamon in your microwave. This isn't even good enough where one could smell it, it's too strong. It took over 12 hours before there wasn't any odor left at all.
Example Output:
Bad review
