I have tried different key organizers over the years and love the concept of these clip on sets. But they were generally of poor quality and broke easily. Not only that, you can't connect them all to the same ring or create something like a starfish shape in your pocket, which is inconvenient. I paid a little more for a higher quality option and they are excellent. They hold well and don't let go when they shouldn't, and let go easily when they should. Each ring set has a large end and a small end. You should attach all of your wrench sets to one set with small ends. That way your keys to your house, office, individual cars, whatever can be in your pocket at the same time and there won't be a mess with the starfish. All eight went in a ring for my keys and they work very well.
