Example Input: The power plug fell out within 30 days of purchase with light use. It won't stay in. Had to buy replacement.
Example Output: Bad review

Example Input: The story was not bad but the &#34;mystery&#34; was not very suspenseful nor mysterious. There were things that I really didn't like about where it ended. I hope this writer will keep writing but change up some of what she is doing. She did try to do too much for me in these first two books. For a novella, it's okay. It takes all day long to read. Her stories are going downhill and that's just sad.
Example Output: Good Review

Example Input: This mouse is worthless. It does not track on my glass table and will randomly change position for no apparent reason. Also, it constantly looses battery. The cord needs to be at least 3 feet from the mouse. I would never recommend this product again or purchase from Anker. Please don't, repeat don't buy. Horrible item. Save yourself your time and money. Buy a Logitech. That was a good purchase. I hope you find this review helpful.
Example Output:
Bad review
