Quality: This fits fine, but the ring in the center was delivered without the 2nd screw to hold it in place. Had to procure a separate similar screw to fully testy this product. Once the screw was installed, the item is a little rigid with "sharp" corners that dig in. Perfect for that sort of kink. If you are looking for something soft, this is not your buy! Let's face it, if your searching for this item, you are not into soft! ;D
