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

Example Input: The case is great but my kindle was too big for it
Example Output: Negative Review

Example Input: Piece of crap!! Full Charging last 10mins
Example Output: Negative Review

Example Input: The battery that arrived looked liked a 55++, and did fit in my laptop, but it was labeled as a 47++, which should look different and is not compatible with my computer. When installed, it showed as only being capable of charging to 40% of its original capacity.<br />I have emailed the seller and I am hoping they will send a genuine item or refund my money.
Example Output:
Negative Review
