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

Example Input: The last thing you expect is to receive a product that simply does not work. It happened with the fan of the cooler master hyper 212. It simply would not work, probably a broken wire internally. Have tried to connect it to different power outputs in my mother board, but finally realized it was burned. Now I need a new fan, probably from a computer shop nearby.<br /><br />I wonder what kind of quality control they have at Cooler Master. I had them as 5 stars supplier for cooling stuff, but now i have to give it then no stars at all!<br /><br />Another thing that needs improvement is the installation instructions. It's very confusing, too much details and small fonts and illustrations. If you are not an experienced computer guru you will spend about an hour to figure out how to assemble it.
Example Output: Negative Review

Example Input: Pros: Handy USB charging port. Universal plug adapters fit any laptop.<br /><br />Cons: Charger will shut down if AC power is briefly interrupted, and will remain down even after AC power is restored. You have to unplug the AC power cord and plug it back in to reset it. Forrest Gump could have designed a better charger.
Example Output: Negative Review

Example Input: This case not only looks nice, it works great! The stylus loop is an added bonus. I highly recommend this iPad case!
