Example Input: This product is great for adding a very pleasant color to your home. I love using the product. It does smell like lavendar but so does lavender. So far it's been great. The diffuser lasted two weeks with regular use. I'm happy and you will be too. Thank you.
Example Output: Good Review

Example Input: Great product that is low priced.
Example Output: Good Review

Example Input: This is a good book with some useful ideas but it lacks the clarity and organization that I would like. Not all of it's tips are easy to follow even though many seem reasonable or logical. Also, most of what was in there had been said before by other people. You will no doubt learn something new here but your brain starts making connections that you have not learned before. Like everything else in my opinion, take this advice lightly.
Example Output:
Good Review
