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.
Example: These are junk! Both bulbs have burned out within a two month period!! I cannot believe that this company can be in business with such poor quality. I have used infrared lights for my ball python for many years now and I get a varied range of months from a bulb, but I have never gone through two bulbs in a matter of two months! I am very disappointed.
Example solution: 1
Example explanation: The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, he gave 1 star to the review considering it extremely poor

Problem: It's hard to know how many stars to give this product because 1) on the one hand, it stopped working less than a month after I received it, but 2) the company honored its warranty and sent me a brand new one with no trouble at all. I just received the new one, and I really hope it has a much longer working life span than the first one I received last month!

Solution: 4
