Instructions: In this task, you're given a review from Amazon. Your task is to generate a rating for the product on a scale of 1-5 based on the review. The rating means 1: extremely poor, 2: poor, 3: neutral, 4: good, 5: extremely good.
Input: The only thing I would change is the size of the mesh filter which has a very small capacity. I have to fill it about three times and then it loses enough heat I have to nuke it because I add half and half. But, I really like this unit a lot.
