Good quality. Metal support is the wrong shape - it angles in and pokes into the wrist right at the base of the brace and cuts off circulation. Thumb hole is too small - cuts off circulation to the thumb. This must be designed for very fine-boned women. For reference, my wrist (where it meets the hand) is 15.5cm diameter and 17.5 cm diameter at the base of the brace (where there is muscle). The inner sleeve for "effortless application" is a great idea in theory, but while it is made from stretchy material, there is no way I was ever going to get it to stretch enough to keep from cutting off circulation. Had to return both right and left.
