Example Output: positive

Example Input: This was a steal! For 13.00 one would never know it is a pre owned case. It saved my phone more than once when it slid out of my lap while I was getting out of my suburban. The only thing I would change is making a belt clip for it to be worn on your person. Other than that AWESOME!!!! I'm a happy girl.
Example Output: positive

Example Input: I am so excited to get this sweat vest! Fits great zips up easily. Fits and stays a lot better then a normal sweat band or waist trimmer. The smell of the material goes away as soon as you soak it in water with soap. But all and all great product.
Example Output:
positive
