Definition: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: I got a similar set (3-pc with shaker and 2 glasses). I agree with the other reviews about the shaker, it leaks a little bit. I suggest getting another shaker, but keeping this one around as a back-up OR wrapping a small towel around the leaky seam. I like the texture of the shaker and glasses. It's classy and not so overdone that it's tacky.
Output:
Positive
