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: I wish I had read the reviews more carefully earlier. These mats are leaky. The first time I used the it was for ink watercoloring. The pigment leak through and stained my desk. The mat was permanently stained also. I used high quality mat (made by Ranger) earlier and never had this problem. These mats have rough surfaces, completely different from the smooth surface from high quality ones. The only thing I like about this product is the size. But what's the use if it leaks? Pretty much equivalent to directly crafting on my desk.
Output:
negative
