I bought this product to support a sprained thumb which is already arthritic and was exceptionally painful on the joint at the base of the thumb going down the thumb 'pad' to the wrist. Indeed the product was just what I was looking for giving both relief and protection from 'over working' it. My only complaint is that the top velcro around the thumb isn't quite long enough to cover the base velcro leaving a gap at the end - particularly if the pad of the thumb is swollen as mine was. This means that it does 'catch' on clothing/tights etc,sometimes anoyingly plucking these items and picking up fluff leaving it quite scruffy looking. However, thumb supports are not easy to find and this product does do the job.
