Detailed Instructions: Given an Amazon review, indicate whether it is a 'Positive Review' or 'Negative Review'.
See one example below:
Problem: I was very surprised at the high quality of the stitching, the sturdiness of the handles and the padding for my laptop. The price is amazingly low and the look is very good. I am quite happy with this purchase. It fit my MacBook Pro perfectly, with a little bit of room to spare.
Solution: Positive Review
Explanation: This rating is correct based on this review provided by the user as they liked the product very much and they were surprised that product is so good.

Problem: Clearly the worst piece of hardware I have purchased. If you have already purchased it, save your receipt, and be prepared to pay to ship to the facility, and back to yourself. Have you ever heard of that? It will break in your first year. So, be prepared. I chose not to pay to replace it. Why pay more money to get a refurbished piece of junk.<br /><br />Do this. Forget the 650w, if you want to pay less. Better to get a 450 of 500w name brand. VisionTek will be out of business soon with their unreliable product backed by a substandard warranty.
Solution:
Negative Review
