Example Input: My son wanted this hat for his birthday. We ordered it 2 days early and when we opened up one package - there was only 1 hat. So they sent us another one. We got that in less than 48 hours. On top of that, it doesn't fit right. It's really small. He can't see out of it....looks pretty bad. Don't waste your money.
Example Output: Bad review

Example Input: First I'd like to say - this item is an absolute must if you are shopping in Amazon.com.
Example Output: Good Review

Example Input: This product could just be my personal issue with the way it makes me sweat. I used this as part of a weight loss program and it did not work. However, as a daily deodorant - yes, very good product. Will try again.
Example Output:
Good Review
