Example Output: positive

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: I bought these bags as a newer and smarter alternative containers vs the vinyl and clay pots I’ve previously used. I don’t have to worry about the plants getting waterlogged roots with too much rain as they have the ability to grow better. I know that they are lightweight to move and hope they will me for years.
Example Output:
positive
