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.

Let me give you an 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.
The answer to this example can be: negative
Here is why: 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.

OK. solve this:
I absolutely love this helmet. It is so hard to find a helmet that fits my kids' head properly, however, this fits perfect. The thing that I like most about this helmet is the adjustable back. My three year old and five year old can both wear this helmet, which is great! I wasn't sure if this would fit my five year old, his head measures 55 cm, but the small was a perfect fit. The helmet also has a padded chin strap which makes it comfortable to wear. My three year old often refuses his helmet, but I had no problems with this one.
Answer:
positive
