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 was pretty surprised at how girthy it was when I opened the package. It is made with quality materials. There was the usual strong odor that tends to come along with new toys. But once soaped up nicely it seems much better. I feel lube is nessecary as a companion with this toy. Which can be a downfall at times. But the fact that it operates very smooth And quiet makes up for this. Overall I am very pleased with this purchase and this brand. I love the fact that the batteries are kept in a tray that makes it super easy to keep them together and ready to go in between uses. Great price, good investment, great pleasure :)
Solution:
Positive
