Example Input: We have about 10 spinners in total but this one is the best. My 4 year old collects them. This one has a long spin time and lots of light patterns. Cool both in light and in the dark. I’m so glad I got this spinner for him. Well worth the money.
Example Output: positive

Example Input: I absolutely love these! I've never installed something like this before. It took me a little longer than it prob would have taken most men, because I didn't think the directions were quite clear so I had to do some thinking on it but I'm proud of myself.
Example Output: positive

Example Input: I watched YouTube videos, learning how to use for it and myself. Just put it on the skin tag. no need to poke into your skin. It is a little painful, but it is not that bad. I'm so glad works really good.
Example Output:
positive
