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: Consider Input: This is the second "Tug-a-Jug" food puzzle I've purchased for my wire fox terrier. The first lasted about five months until she chewed through the rope. But this toy kept my dog more occupied than any other food puzzle I've tried, so I decided to purchase a second one. My plan was to put this one away as soon as my dog was done with her food so she wouldn't "play" with it and chew through the rope. So in other words, I blame my dog's destructive terrier prowess on the demise of the first toy rather than the manufacturer. But after just one week of use for the second toy, the bottom part where the end seals onto the main container literally cracked and shattered into many pieces when I was sealing the toy. My dog may chew through ropes but she's not that rough with toys, and I was using normal strength to twist the end piece on, so I'm pretty sure this one was a dud. But after that, I'm totally done with this company. The shards that came off in my hand were tiny and sharp enough that if just one shard had broken off without my notice and go mixed in with my dog's food, she probably would have ingested it and had internal bleeding.

Output: Negative

Input: Consider Input: these are grossly overpriced. It is a package of three boxes but when you take into account that they are a dollar of two per box than they should be, you then have to pay for shipping. Sorry, I would skip them. My local grocery store carries them and a box is anywhere from 2.98 to 3.49 each. Although these are healthier than some other cookies, you still have to watch the fat, sugar and salt contents. Whole foods are much better for you but in a moment or two of indulging, these fit the bill. Just the price on this site is ridiculous! Ask your grocer to start carrying them.

Output: Positive

Input: Consider Input: This used to be a great food, but they've changed the formula and my dogs have suffered. Their customer service is very rude. My dogs showed signs of distress within the first 24 hours of eating the new formula. Explosive Diaherra, Vomiting, Fur became dull. Change it back Canidae!!!
Output: Negative
