Example Input: I’ve been having knee pain for the past few months so I decided to try this support brace. I can’t believe how much support it does provide and my knee pain has gone down significantly. It’s slim so you can wear it under pants while at work but also looks fine with shorts. So glad I found this and it is helping with my knee pain!
Example Output: positive

Example Input: These worked out wonderfully for our event! I have to admit, I was skeptical at first, but they were soooo much better than I could have imagined! And a great price!
Example Output: positive

Example Input: The pads that were described were NOT the ones that arrived. When wearing a neck brace for spine surgery, you cannot mess around with incorrect products. The pads were not even the ones that were pictured on the package insert. Now I have to have someone drive more than an hour to a medical supply store to get the correct pads before I can get out of bed. TERRIBLE.
Example Output:
negative
