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

Input: Consider 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.

Output: Negative


Input: Consider Input: This thing is awful. Prints magenta only. Drives me crazy. I am going to go find a high building to throw it from.

Output: Negative


Input: Consider Input: The product title is incorrect. This card is 10MB/s (up to 66x). That is what it actually says on the box, not 133x. It isn't a problem for me because 66x is plenty fast for my panasonic fx30 camera. But if you really require 133x (i.e. 20MB/s) this is not the card for you.


Output: Positive
