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]: Product was never received nor money returned. Four requests have been ignored. I will probably never again order anything through Twang or from Amazon. Also, I will spread the word about these sites.
[EX A]: Negative

[EX Q]: There is contradicting information. The description says Senior Greenie Large, while the photo shows "regular" as well as 27 treats versus 27 ounce. Anyone that reviews and can clarify the actual product would be much appreciated.
[EX A]: Negative

[EX Q]: I did not realize until I received this product, that it contains propylene glycol. To be fair to the seller, if you read down the amazon page far enough, that fact is stated. However, I find the thought of ingesting propylene glycol disgusting, so I am going to search for a replacement that is pure natural lavender.
[EX A]:
Negative
