Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I thought this would be good to try because I love the floating beads in the other rabbit vibes. I am a single gal, solo practitioner so to speak, and found that the steel rotating balls are just not comfortable for me. They are too hard with no give and get quickly uncomfortable especially if you squeeze your muscles. I can usually have one orgasm with this toy but not the multiple orgasms with the more comfortable rabbit vibes with the pearl beads. It's okay but it just doesn't get the job done for me.
Solution:
Negative
