Instructions: In this task, you're given a review from Amazon's food products. 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 or mixed, 4: good, 5: extremely good.
Input: I am sorry to say I had trouble with the cups themselves. Each time I used them, my machine would say "decalcify" which I did the first time. When I used them the 2nd and 3rd times, the problem occurred again. I was able to clear the hot water spout with a toothpick, which remedied the problem. I will not use them again, though, because I don't want to have to do that after every use.
Output:
