I have been using one of these for 12 months off and on now especially when doing heavy work to assist and support my wrist. It is showing signs of wear and tear, especially the section around the thumb which wore very quickly (within a few weeks) but has literally hung together on a couple of threads for about a year of hard use. The other hard wear point is the metal support on the top of the hand broke through its pocket about 6 months ago.
This is a great product for the job, especially in winter. The velcro grips well (although I have had no issues with it being too difficult to remove) and it is comfortable especially on one drives giving my wrist great support. It loses a star because of the weakness of the design around the thumb area.
But to reiterate, my brace has done some hard yards and whilst worn out did an excellent job. I highly recommend it.
