Given the task definition, example input & output, solve the new input case.
In this task, You are given a review of Amazon's food products. Your task is to divide them into two classes: negative or positive, depending on the content of the review.
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.
Output: negative
The user seems very disappointed in the product. Because the bulb they ordered has been burned out earlier than usual. So, it's a negative review.

New input case for you: This flat iron/curling iron actually works. I was looking for a cheaper alternative to the Tyme curling wand thing. I just got my package today and immediately plugged it in. I have bleached hair so I set it on the medium heat, or one close to the middle. I literally had curls like 2 minutes later. The first swipe straightened my hair. Then I remember another reviewer said you have to turn the barrel as you go down the hair, so that's what I did. I sort of kept wrapping it as I was sliding it through my hair. One important thing is to make sure that little lip on the wand is the side that is close to your scalp. I forgot that part and accidentally singed my forehead, I hope the burn isn't too bad! Anyway, so here is a picture I took. This literally took me like 5 minutes on dirty hair. All I did was brush out my hair and pop in a few curls, VERY pleased with how easy it is. It does sort of pull on your hair a bit, but I'm sure I will get better with that in time. And yeah, they aren't perfect, but this was my first time and I wasn't going for perfection, I was trying to see if it worked. I hope this helps someone else make the decision. Oh yeah, my hair type is fine.
Output:
positive
