So far, so good...
I've been using these for a while now and love them. Once my key ring started to look like I was a grade school janitor, I wanted something to separate my basic keys (car, house) from all those others I used on much rarer occasions. These were the perfect solution because I can still easily carry them all without having to wind everything around those key rings and pinch my fingers. A quick button-press and they separate, and I can take those two meager keys with me for quick errands and leave the other behind.
