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.

Ex Input:
This mat is so small, and as others have noted, the "turf" is pointy - so it probably hurts cats' paws (it hurts my knees!)  My cat jumps right over it and I end up with litter kicked up all over the place.  Seems like a good concept, but I would bet it doesn't solve most people's problem of trying to contain the litter.  I just bought an extra large Petmate Litter Catcher that has 4-1/2 stars.  Hopefully, I'll have more success with that!

Ex Output:
Negative


Ex Input:
Shake N Bake is one of those products that has a limited market. While I like the crunch factor, it can be hard to keep the chicken from getting soggy on the bottom. It's really a glorified breading which is about as easy to make as boiling water. If you like it fine, but for me I'd rather make a dish from scratch.

Ex Output:
Negative


Ex Input:
The bottles were both leaking badly; about half the product had leaked through the bottom of the box.  Unfortunately they cannot be returned, so I just wasted money ordering this.

Ex Output:

Negative
