Input: Consider Input: This was my first purchase of a vibrator and was very disappointed. It was shipped very discreetly from Amazon directly, but it didn't work. I put in fresh batteries and it wouldn't turn on. I even tested the batteries, they were good, but this rabbit wasn't. Unfortunately, Amazon doesn't take returns on this type of personal product. I simple won't buy anything made by California Exotics again. I'll try one of the other brands next time.

Output: Negative


Input: Consider Input: I had almost all of the Jean Auel's books and needed this one to complete my collection. It turned out to be a book club size and I traded it to a friend for the full size version.

Output: Positive


Input: Consider Input: A typical Patricia Cornwell fiction novel, easy to read and a page turner. It gripped me until the end. Enjoy.


Output: Positive
