A great invention because you can sort one of the rings and take as needed or leave home function related to each key.

The keyrings are flexibly connected to a stable strut, at the end of a ball is attached. The key holder has an all-round rail with a semicircular opening at one edge of the rail, which is blocked by a spring mechanism. With a thumb movement considering the small metal collection in the round middle part of the key holder in the middle and then move one of the key rings in the resulting shared opening. It's that simple latch or unlatch! Accidental disengagement is impossible humanly. I have in over 10 years, yet had not a single case in which a klinkbarer keyring would be accidentally released.

Why not 5 stars?
This product would have to actually conquer the world and are sold in every Locksmiths and locksmith. By apparently very restrictive patent design, there is the system but almost nowhere in business. That's a real shame, not a reason for me would still be deducted a star. What I miss painfully, is the ability to purchase individual klinkbare keyrings without mitkaufen a holder with carbine. For this and only for that I subtract a star. Who does not interfere with, can access safely.
