So far so good, time and use (large frames) will tell. I can't for the life of me make it small enough for a 5X7 frame. It was necessary to use a shorter carriage screw to make it smaller as the screw provided interfered with the small frame I was trying to make. None of the edges were cleaned in the making of this item. If anyone can give me any advice on how to make a 5x7 frame I'll be happy to edit my review.
