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