Query: very good product

I have been wearing this product on both elbows for weight lifting and MMA practices. I has decreased my symptoms and allowed me to perform better substantially. I also have less pain after the practices.I am 43 y/o, and I have had problems with my elbows since I was 16, so I have had many other elbow supports. Now that I washed them once, they have become more comfortable too, to the point I find myself wearing them until I get home. Very happy with this product.
