Example Input: I bought this outdoor Christmas Projector Lights so I can be ready for Christmas. It can be used outdoor or indoor. It has nice snow fall down effect + other Christmas theme images which will make the outside of house looking perfect.
Example Output: positive

Example Input: I really like Pippa's writing. This sci-fi slash fantasy combination has me hooked. Cannot wait til the third book is released. Plot keeps you guessing about what challenge will come next, and how will the character grow with it. Please keep this series coming...quickly preferred. ;-)
Example Output: positive

Example Input: Was never delivered. I asked for a replacement and that was never delivered. Instead I got a notice that they processed a refund. I just wanted the dang toy.
Example Output:
negative
