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.

[EX Q]: This item was much shorter than I expected it to be. I have an alaskan malamute and this did not do the trick in trying to help with his pulling. If you have a small dog, this will work for you.
[EX A]: negative

[EX Q]: This product makes you scan a QR code that goes to a Chinese(?) website. When you scan code it redirects you to an app which you have to download. Very sketchy. Don't buy, spend the money on a legit apple product.
[EX A]: negative

[EX Q]: Product damaged (chipped glass) when washing on top dishwasher shelf after only a few weeks. Inferior materials and product. I am very displeased with the quality of this item. This happened to several items in our set so not a "one off" defect.
[EX A]:
negative
