The insert shows a pack of 5 regular sized titanium rings. My package contained 3 regular sized titanium rings and 2 much smaller typical split rings, similar to the smaller rings found on most proximity keys. Regular sized rings seem very ergonomic and easy to use. I just received it today so can't comment on durability. I'm just very disappointed that I didn't get the full size 5 titanium rings as advertised.
