Example Input: I love the quality of this item. Pros:It locks securely. It is adjustable to take your glasses and not get in trouble for them being too big or small. The arms are super strong -- I can put on my eyeglasses, sit down, watch television, then lean back against the arms. Cons: Mine came without a manual. There was no paper contact with where it goes together. And no instruction sheet.
Example Output: Good Review

Example Input: Have used their batteries in other products including lights and flashlights. I don't have to worry about the price because they are a good value. The work as well if not better than Duracell or Energizer batteries. Good product! Highly recommend. We will order more when needed!
Example Output: Good Review

Example Input: A very good product.
Example Output:
Good Review
