Question: 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!

Answer: positive

Question: I love these pots. My violets love them as well. Continuously blooming. I can see the water level so I know when I refill it. Taking the bottom off to wash is easy cause there will be green moss growing. I order 20 of them and two of them leaks at the bottom cause the plastic is not very strong. so I use the calk to seal it. No problem!

Answer: positive
