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.

I have put different treats under each of the yellow covers however, as hard as my dog tries she cant pull the yellow thing out of the hole. I think the holes are too deep making it impossible for a small dog (she weighs 9) to get it out. She was bored with trying after just a few minutes. She was smart enough to know it wasnt coming out.
Negative
