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

Example Input: The story started out well for an erotic novel and got more interesting until the end. It just became a book of sex then love story. So I am in no hurry to read any more. Sorry!
Example Output: Good Review

Example Input: The unit itself is great - works wonderfully as long as it works. And since the battery life has also declined significantly, one must wonder whether this will continue. One thing at a time. I have not contacted Coby to see if they offer an alternative. At some point, even their own products need more than 20 cents worth of work in order for them to sell them. This should all be taken into account before putting out faulty products.
Example Output:
Bad review
