Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: This product does not work with my ibook G4. As stated by some earlier reviews by other customers, the charger toggles between charging and not charging. Occasionally, if it is left on, it will continuously charge. I thought about keeping it, but it is unreliable and there are other third party options for $10 more.This one is going back to Amazon.
Example Output: Negative

Example Input: This thing is freakin awesome! You can stand it up, lay it down, or rearrange to your liking. They are sturdy enough to hold several things: shoes, baby bags, blanky, and more! I use them as cubbies for my kids so they can stuff the things that we take with us everyday in there. I love it, and I am planning on getting more.
Example Output: Positive

Example Input: I had these bowls on my wedding registry and my sister in law ordered them for me. The first time they came, they were all broken and cracked. We thought it was probably during shipping that it happened so we sent away for a replacement. The second set came, and two were in tact, the other one had a crack down the side. I just let it go and continued to use them...well....4 months later, they were stained, they ALL had cracks in them, down the sides, on the bottom (which means that anytime I put liquid in them they leak). They are practically falling apart after 4 months of use. KitchenAid can do better than this...I was very dissappointed!
Example Output:
Negative
