I really like these keepers. They are longer than the other ones I have & because of that, I don't get stuck with the end of the pin. So far they have kept my pins in place with no problems. They are a little hard to install only because of the fact that they are so small. The mechanism securing it is not the problem. I definitely would recommend them.

The initial setup was difficult with bad eyesight. But I took an evening watching tv and did it by feel while catching up on WandaVision. Once they were started, they were easy enough to tighten onto my pins. The fit Disney pin great. The back of the pin will break off before these abandon ship. I'm glad I wont lose anymore pins when they're on my lanyard.
