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

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: I think this is a case of my expectations being too high. I was so encouraged by the great reviews of this product, I really was expecting a miracle. After only wearing this twice, it is stretched out. At first, I thought perhaps it would regain it's shape after a few hours but nope! It's no better than a cheap, fashion corset. It will smooth things out so there's less bulging under the clothes but I was looking for a real "waist trainer", something that would go on tight and STAY tight. Considering I found this product when I searched specifically for "waist trainer", I would say the claims of this product are misleading. It is shapewear, it is NOT a "cincher" or a "trainer".

Output: Negative


Input: Consider Input: I bought this air mattress two months ago. I used a couple of days and it worked fine. Now a friend is planning to visit so I decided to use it again but something went wrong, instead of a flat surface, there is a huge bump in the middle that would make sleeping on it uncomfortable if not impossible.Since this is a product you will use only a couple of days before putting it away until you need it again, the amazon returning period will be over by the time you actually try it and find something wrong with it. And the company that makes this mattress says "this product does not have any warranty or service program". I hope I can put this in the recyclables bin!I wish I would've spend a little bit money on a real mattress that won`t fail after a while.


Output: Negative
