Example Input: Nice book, the only thing I didn't like about it was that each time a new topic came up throughout the first 30 pages or so we learned more than needed and it wasn't very interesting. It also gets a little boring around page 100 but does pick up. If you think you're going to take pictures of every bird in a local neighborhood, buy several books on your own first, this book is an okay one for that.
Example Output: Good Review

Example Input: This heater works really well. You set temp's to desired amount of temperature,its a lot like a big space heater. It will blow cold air into room very quickly.
Example Output: Good Review

Example Input: I was looking for a good replacement phone - this fit the bill. Works just as well with Vonage or our old Ooma system - only slightly lower quality sound but you can't beat it for $19.95 per month! Good value & worth it. I'd buy again...
Example Output:
Good Review
