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.
One 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.
Solution is here: 1
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

Now, solve this: Although I'm worried that the 2nd replacement b/t transmitter also died after using it for about 4 hours each evening for about a month, the replacement does work well to power b/t earphones with quality sound. Also pairs easily with the earphones. If it continues to function I will be satisfied. I must say that the SunValley /TaoTronics customer service is 1st rate!
