Example Input: The main thing I got out of this book was to take note of the difference between a'market' and what an artist thinks a market could be. While the writing is fairly competent, it can not be taken as completely self-serving. It seems to suggest that if you give them enough money they'll keep coming, but they won't. There are some interesting ideas there, but they're scattered amongst the clunky writing.
Example Output: Bad review

Example Input: This product works flawlessly with my Windows XP and OS X - just plug it in a USB port or use the included software. The print quality is very good and I am quite satisfied at this price. I've been using refilled cartridges for about 2 years now from various sources but found that most of the time, ink dries up within 1-2 weeks time when you refill them. These re-manufactured cartridges are great to buy, they don't leak as far as I'm aware and work perfectly.
Example Output: Good Review

Example Input: This product is a great deal and works just fine on our Sony camcorder. Price was definitely right! It came faster than we expected too. No complaints, so far, of any kind. Thanks! :)
Example Output:
Good Review
