Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.

Example Input: After carefully following the instructions several times and getting unsatisfactory results, I contacted technical support. Their answer: \"Compared to default yes it appears warmer, but that is expected.\" What a waste of money.
Example Output: Negative Review

Example Input: DOA. Drive not recognized. I had purchased a few of these, so I tried one of the others and it worked in my computer. So, that confirmed that it's a DOA and not the computer.<br />I had to pay $14 shipping cost to return it to WD.<br />The replacement they sent was also DOA. Now I have to spend another $14 to return.
Example Output: Negative Review

Example Input: I recently purchased this keyboard in mid November as a Christmas gift for my teenage daughter to use with her Samsung Galaxy tablet. The keyboard does not work, and because I bought it more than 30 days ago, the company will not allow me to exchange the keyboard as they have a 30-day warranty after purchase. The brief instructions do not include a phone number to call if you have questions or problems.<br /><br />If you do decide to purchase this keyboard, be aware of the 30-day warranty, as the information on the listing does not mention this.
Example Output:
Negative Review
