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: First off they don't give enough washers to assemble properly. It's difficult to assemble. Once assembled the feeder bar plugs very easily with fertilizer even with dry fertilizer but has slightly soft pellets. The material I was using has a black pellet that plugged the feeder bar. The 3 bags gone. $150 bucks. Most fertilizers now have soft pellets. This thing plugs them in the feeder bar and it turns into a solid bar. It needs a different feeder bar to work with today's fertilizers.
Example Output: negative

Example Input: I have used this for my terrible joint pain from being on accutane. It has helped me so much! I have also used it on my husbands back for all the pain that he always has and he found relief from it too! So excited I found this.
Example Output: positive

Example Input: Poor build quality and not even half as bright as my stock halogen blinkers, and the one behind the exhaust melted on the first ride. Don't bother buying these, oh and mine were wire backwards so red was connected to black and black to red to get them to work.
Example Output:
negative
