Out of nowhere I suddenly lost a key, which is previously never happened to me in 40 years, after all. A glance at the solitary remaining part showed that the resilient balls missing, who are responsible for the maintenance of the counterpart. For safety's sake I once took a look at the clutch of my wife: and there was exactly the same problem - the next key loss would have been only a matter of time ...
Maybe we were just unlucky twice, but on another attempt, we will certainly not take a chance.
In our experience, I can prospective buyers from purchasing the product, unfortunately only advise.
Allen, who own the product, I suggest regular monitoring of the parts and keep my fingers crossed that nothing is lost ...
PS: We had the couplings with the engraving "Swiss Made".
