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 installation of the weather-stripping is fairly straightforward. It takes a bit of strength but once you get the hang of it goes pretty well. I used the plastic screen installation tool. Getting the old weather-stripping out of the track is somewhat tedious, putting the new weather-stripping is "fun".
Output:
