I bought 2 of the Key Ring clutches because we occasionally swap our cars and the private key can then easily be repositioned on the car keys, so that you do not need extra keys. The delivery was super fast. The quality is also great (Swiss made up), and the inputs and disengagement is playing easily, the connection is nevertheless bombproof! The product is absolutely worth its price! The only downside is that the thing is a bit long. Here is still potential for optmization.
