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: This little light exceeded expectations. I'd been using an older light that ran on two AAA batteries. My wife gave me the Cygolite headlight as a gift, and the rechargeability appealed to me, so I ordered this so I could have all rechargeable lighting. It's pretty hard to be dazzled by red light because of the way the eye works, but this sure as hell dazzled me when I first turned it on, facing my eyes. WOW. There are lots of modes to cycle through, from short and medium flashes to dim up, dim down to solid ON. It takes a minute to get used to holding down the button to turn it off, but once you've got that, the light "remembers" what mode it was in when you turned it off, and comes back to that mode when you turn it back on, which to me is exactly the right behavior. Love this little light!
