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

Input: Consider Input: This product requires a stereo player in which the balance is turned totally to the left. Most auto systems have that capability. However if you have Dolby or SurroundSound, it can be difficult (and maybe impossible) to play the cassette without hearing two recordings at the same time. Unfortunately neither the packaging nor the website will warn you of the problem. You therefore should think before buying. Once you have opened the packaging you may be unable to return the product.

Output: Negative


Input: Consider Input: At 80" iong, this is an extra long twin, not a standard twin. Consequently I had to take back the sheets I bought, as they were 5" too short. I would have ordered a different model had I known that 80" wasn't standard. It's easier just to replace the sheets and I don't have time to send the bed back.

Output: Negative


Input: Consider Input: I got this book free for my Kindle. I have read a lot of free Kindle books and most of them are not that great, but they are at least a little entertaining. This is the first book I have deleted before finishing it. I read to 35% and just could not take any more! It was not funny at all, it was super annoying and predictable.


Output: Negative
