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: Had to return it several times for a close enough fit. A size XXX is actually a large adult size and medium fit around the arm/shoulder area. Finally gave up and got a full refund.
Example Output: negative

Example Input: This is an awesome uke stand! I teach public school and have to keep mine separate from the rest of the class, this holds it perfectly and it's very sturdy. Don't hesitate to purchase!
Example Output:
positive
