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

Example Input: Absolutely avoid this seller...if you have a problem in the future he will treat you like dirt.<br />We bought an iPad a year 1/2 ago, and not only he did not include the serial number on the invoice but he continues refusing after numerous requests ( by the way, he simply does not reply after second request). Apple requires the serial number on the invoice otherwise will not help you...which means the iPad we purchased is absolutely worthless.
Example Output: Negative Review

Example Input: A device that should be sold in computer retailers. I cannot believe that this is not available at Best Buy or even the Apple Store. I found something similar, but as a complete pack with other device connections. This is being sold at a great price and works flawlessly.
Example Output: Positive Review

Example Input: The product works beautifully and is to my expectations. The light and the leather cover really finches the kindle off nicely
Example Output:
Positive Review
