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

Input: Consider Input: With the type of closures and the amount of compression it is meant to give it's really difficult to put on. You need a hand to pull it closed in order to actually be able to close each of the 20 some odd hooks.

Output: Negative


Input: Consider Input: I purchased the Intex airbed to replace an Aerobed that our cats "loved" too much during a guest visit. Comfort wise, the Intex wins hands down-supportive yet comfortable as well. Convenience wise, it inflates a little slower than our old Aerobed (albeit, there is more to inflate) yet it takes up less room when rolled and stored in the sack that comes with it. The only reason I didn't give it 5 stars is because it is VERY high, so a restless sleeper can fall off pretty easily.

Output: Positive


Input: Consider Input: I ordered a Canon camera battery. NB-5L.Some company (not Amazon) sent the wrong battery.I tired to send it back. Too complicated. (Many emails, lots of forms.) I found someone who needed the incorrect battery (NB-4L) and gave it to them.Then I went to a real store and bought the correct battery.Bad taste in my mouth remains.


Output: Negative
