I was looking for some solid keepers since we switched to nylon gear. Saw these and thought they would be the solution to my problem. Not so much. The keepers arrived snapped. I have yet to fully unsnap two of the keepers. And for the skeptics, I've torn the skin on my hands on the polymer edges trying to unsnap them. Construction seems solid (obviously) but they might have over-done the retention on the snaps. The snaps are bending before they'll give way.
