Example Input: This little radio works very well for listening in on weather reports while out camping.
Example Output: Good Review

Example Input: This is an excellent product. It replaces a unit that broke after some time. The old one had the battery door open and needed to be recharged. You need two AAA batteries. It's lightweight - good to travel with. Batteries can last 2-3 weeks between charging. All in all I'm very satisfied with performance - no complaints.
Example Output: Good Review

Example Input: I bought the Kindle version of this book thinking it would be much easier than trying with a paperback. It is not. You have take an active part just like in real life, which makes you feel that you are really there.
Example Output:
Good Review
