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 returned this item right away. It did not work for my husband at all. He could barely hear anything. And no headphones, just the ear buds that come included. Not worth what it was...
Example Output: Bad review

Example Input: This Oxo product is very handy when working on dishes that get water in them or have food stuck to it.
Example Output:
Good Review
