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

The product, a kindle is not new but a replacement for a kindle purchased some 17 months earlier and which ceased to function. It was out of guarantee so I had to pay 50 for a replacement, including delivery and return of defective kindle.The replacement does NOT come with a guarantee which I consider unfair. I was going to upgrade to the Amazon tablet and give this kindle to my wife but not now!! Apple might be a better bet.Amazon does not seem to know I have a new product as recent purchases have been delivered to my Archive not my kindle. All in all, I am not a happy customer.
Output:
Negative Review
