I bought this for my father who is suffering from back pain, and drooping left shoulder. He needed support, this product is made well and does support and help him, my only complaint is it is very difficult for him to put this on himself at his age ... he has poor mobility and hard time grabbing straps . I wish it was designed more as a vest , he would be able to use it on his own then . Elderly will have trouble with this one . He can't do it alone.
