Example Input: It worked for a month, I can't complain. The first problem was that my new monitor would not pick up the signal, so i tried several other sources before calling HDE support (which takes 3 days!). They said it must be some kind of interference etc. So all i needed to do was return the whole system and get another since we were getting no signal at all. They agreed to refund my money. Well that's when things got really bad as far as customer service.
Example Output: Bad review

Example Input: This book is short with only 26 pages. If your looking for a very basic overview then this would be fine but i think people wanting to understand economics will most likely get just as much from reading my blog.
Example Output: Bad review

Example Input: I was really disappointed, especially considering how much I paid for it. There are barely any pages and there isn't a single recipe. Just random thoughts. It is not what we were looking for. And I'm also shocked to find that it says you must only use organic ingredients. Well, who knew? How on earth do they get around the fact the animals have to be killed?!? Not cool... don't buy this book. Very disappointing.
Example Output:
