I had ordered the Large size of the knee brace and when it arrived I tried it on but it was too big. So I had received an email from the vendor asking me how the product ifit my need and for my feedback. Before thinking of returning the product i was going to wash it and hoping it will shrink. They had saved me by emailing me, i responded to the email and explained the problem. They answered my email right away next day, and wanting to send the replacement right away and told me to keep the original. They didn't have to do that but willing to and doing the right thing without asking questions even though it was my mistake.
