Example Input: This thing worked fine for 3 months when you plug in earphones. Then one stopped working.
Example Output: Bad review

Example Input: I love this thing. It works so great and easy to clean. It's much better than a standard meat pounder that only has one hole where you can put the meat.
Example Output: Good Review

Example Input: I ordered this to run for a small town marathon, it came in the post quickly and looked good, but as soon as i opened it, 2 of its legs were broken. It really isn't worth taking back...so instead i just cut them off myself. So annoyed!!!!
Example Output:
Bad review
