The large clip and the body work great. The small s-clips are not secure if you put your keys in you pocket. I had a key come loose in less that a day and two more in less than a week. I then replaced s-clips with small split rings and it worked great after that.
I've had the key rack for over a year and it has stood up to daily use. The easy to remove S hooks are super helpful for slipping a key on and off, such as when I want to only carry one key on a run or need to leave a key with a valet. No more wresting with spiral key rings!
