Instructions: 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.
Input: These cups are a great little addition to our household. I LOVE the fact that they are non toxic and I think parents need to really be concerned about the amount of harmful chemicals in all the plastic we are exposed to. These are high quality silicone and passed the "squeeze test" with flying colors. The pop on lids are easy to put on and stay on tight and the colors are really cute too. The size works perfectly for our 2 and I'm very happy with them. If you are considering these it's an easy purchase, I'd do it again.
Output:
positive
