My husband had a really bad knee injury at work, ligaments torn and in a really bad pain all the time. Can’t bend the knee, so driving a car was also impossible which made our lives so difficult. I found this beautiful knee brace 875, but beforehand we purchased 425 and 429x with their Facebook messenger help. The size of his knee was not met with the size we were recommended, so returned and refund, then got the biggest one they have which is 875 XXXL. All the communication between us was done by the messenger, the service was incredibly prompt and thoughtful. When I finally decided to go with 875, the dispatch deadline of the day was already passed. But I asked them to push as my husband was so miserable ever and suffering from lot of side effects from the heavy pain killer medication he’s been taking. They were so kind, they pushed my order through and the very next early morning he was in heaven walking like a little kid!! Such a great support with the hinges, and I tried myself oh I tell you you just don’t feel your knee is even there. Such an amazing support. Over all, the products they have are amazing, and costumer services and support is beyond your imagination. Thank you so much guys!!!!!!! Online shopping can be tricky. But with them, I would definitely recommend to anyone in the world. Again thank you so very much. Well done guys.
