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:
This was a disappointment.  I use other products from this line/manufacturer on a regular basis.  I bought this item as a convenience to carry liquid Stevia in my purse.  The first time I went to use it, the liquid was a dark color...almost black..and I had to throw out the latte I was trying to sweeten.  All the manufacturer's other liquid products are clear, and, in fact, this is titled "clear liquid".  It must have been outdated/spoiled. I had already thrown the packing out, so don't know how it was dated.  I tried calling the Amazon supplier, but the call rolled into voice mail.  It's not enough money to spend time following-up, but it was disappointing.

Ex Output:
Negative


Ex Input:
I paid for 100 k cups but received only 98! This is the second time this has happened.I didn't think such about it the first time. Now I wonder if this happens often or even all the time.

Ex Output:

Negative
