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

Input: Consider Input: The product seemed like a good idea but wish I had read all of the reviews before ordering. The product is not sturdy at all. It didn't come with the number of screws noted on the instructions so I had to go out and purchase more in order to finish putting it together. That was after I spent way to much time trying to decipher the instructions. Also, the clips that hold the bag to the frame are very tight and very difficult to put on and remove. I've torn every bag I've used. I hate wasting my money; but, I'll have to buy a better one.

Output: Negative


Input: Consider Input: The bed needs air refilling more often than I thought it would- every 3 days at the most. So much so that if I didn't pump it, the bed would all be like a water bed with "jelly-like" feeling. To lessen this effect I situated it in a corner of the room against the walls. Further more, what surprised me was the round water condensation on the bed sheet just underneath my (head) pillow in the morning. But what confuses me is that in the evening the bed feels cold (or the air inside feels cold).What I like about it though is that the pump works real fast in inflating- although it is loud for an evening activity.

Output: Negative


Input: Consider Input: This boot is comfortable and gives me the ankle support I've needed for any type of hiking. I look forward to many years of use from these boots.


Output: Positive
