Example Input: This wig started out beautifully. Then it started shedding three days later. After shampooing and conditioning according to the instructions it became a stiff mess .The curls were no longer bouncy. It is dull, stiff and lifeless. I have lace front wigs I paid less money for that are still beautiful after 6 months and several shampoos. I am so disappointed with this purchase! I will never purchase another wig from Amazon!
Example Output: negative

Example Input: This screen protector is not good AT ALL!!! It only has adhesive on the very top, bottom, and a thin line on the sides. This makes the touch screen horrible. Would not suggest wasting your money on this product!
Example Output: negative

Example Input: Had a small dent on the medal top. The seller was easy to work with and saved me a lot of stress. If anyone is thinking of buying this product, don’t loose sleep over it, just buy it! Best quality ever! Love our outdoor egg swing. It’s a show stopper. Kiddos love it and we as parents love it too.
Example Output:
positive
