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

Example Input: I ordered this for my new Macbook Pro Retina. I was really happy with the color and the feel of the case, until attached it to my MBP (Macbook Pro). The top half of cover attaches well while the bottom does not even attach. This product sucks. I have been wanting to return it, but I didn't want to bother after coming back from vacation. Anyway, DO NOT BUY THIS ITEM! Ripoff!
Example Output: Negative Review

Example Input: Fits great. Still using it
Example Output: Positive Review

Example Input: This thing is horrible for the macbook air. The top half is too heavy for the air and this case is so hard to get off, I accidentally scratched my laptop while trying to remove it. Kind of defeats the purpose, no? my fingers hurt soo much from trying to pry this off. It took far longer than it should have (the Speck* case does not have these problems and stays on very well). The only good thing about this case is that the bottom half has openings to allow for ventilation (the Speck* case does not). Even though the MacAir vents at the rear, near the hinge, this still seems like a good idea. However, my recommendation would be to spend the money on a more high-quality case that won't be too heavy and will be more easy to remove. On a side note, mine also came with a defect that caused the case to curve away from one of the edges of my laptop. Really not worth the money.
