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 Input: Product is just as described. Needed a good brush for our family of 5’s many metal water bottles and plastic reusable straws. These brushes fit the bill perfectly. I like the silicone bottle brush the most.
Example Output: positive

Example Input: My 3 year old loves this piano! It is so fun and the microphone is a great bonus! Lots of musical options to use when playing with this adorable piano!
Example Output: positive

Example Input: I’ve used the 3M film on the iPad for years, and would never go without a privacy screen with acceptable landscape-directed privacy (I use a keypad). The 3M has always had great performance (once had a guy next to me ask, “Why are you typing on a black screen?”). The JETech is the only glass option I could find, and in my view the privacy function is as good as the 3M. At half brightness, my ipad screen looks pretty much black at about a 45 degree angle, ie a seat neighbor on a flight or train. I was able to get a bubble-free application on the first try, but I do admit to using the steamy bathroom technique I found on YouTube, which (a) works by knocking down errant dust particles and (b) is sure to get you ridiculed by your significant other.
Example Output:
positive
