Given the task definition, example input & output, solve the new input case.
Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Example: I've read this book with much expectation, it was very boring all through out the book
Output: Negative
Review writer does not like the book because it was boring, therefore it is a negative review.

New input case for you: I was looking forward to some really comfortable gel inserts for my earphones. I thought these would fit the bill, but they don't by a long shot. To begin with, even the smallest size was far too big to fit my ears. The large looked gigantic. I cannot in good faith recommend these. If they develop ones that are sized appropriately, I might give them a try. I gave these to a couple of friends, and even they said there was no way these word work for them either. What more can I say? Stick with inserts from companies like Shure or Westone.
Output:
Negative
