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.

Example Input: I've had the other Annie's shells and cheddar and they're usually very good. I wanted to try whole wheat to be healthier, but it's really not worth it. It has a different texture that I didn't like. The flavor was okay but a little bland. If you want a good mac and cheese, stick with the original version from Annie's!
Example Output: Negative

Example 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.
Example Output: Negative

Example Input: These are not black winter truffles (Tuber melanosporum).  I thought the price was too good to be true, (even though they aren't fresh), and it is.  These are Tuber indicums.  It says so right on the label.  I was very angry about this, but JR Mushrooms has said they will refund me for the truffles and even let me keep them.  So I give JR credit for excellent  responsiveness and customer service, although I still feel they should not be labeled "black winter truffles".
Example Output:
Negative
