Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.

Example input: The sound seems really good but sometimes it cuts in and out which is annoying. You have to put the cord directly into your ipod. Other than that, its a simple design with nothing fancy. I love how cheap they were for 10 dollars... But overall nice design... No one can steal me earphones. lol thanks again amazon.
Example output: Good review
Example explanation: Here the review is good because it has positvie tone as the reviewer suggested it really likes the sound and the output is also Good Review.So this example is positive example
Q: This was purchased as a Christmas present for our son so he could listen to his books on tape while working. It is advertised and said it works with an audiobook. The instructions were followed carefully, but still will not work properly. It has been returned (amazon's return policy ROCKS). There have also gone several days in terms of receiving the item due to delays caused by UPS (not always reliable -- you end up waiting months for any shipment).
A:
Bad review
