Example Input: Wow! And not in a good way. I had color treated hair and was looking for a slight tint to cover my grey....well 3-5 minutes later I’m left with bright red hair ONLY in the places that were dyed blonde. Don’t not cover any other places. AND stripped all my other color away.
Example Output: negative

Example Input: Love these sheets! They arrived very quickly. After the initial wash they softened right up. I love the quilted end to the fitted sheet, makes it easy to put on and a snug fit!
Example Output: positive

Example Input: I received the two pans and very poor packaging and one of them worked for about 2 hours and then quit working the other one never worked it all it was cracked the plastic inside the top lid and the button that you push kept on falling out. So it never worked. Very disappointed.
Example Output:
negative
