Despite existing reviews in terms of "quality" I ordered 5 piece, because I need that. I have all five examined and am of the opinion that the mechanism is "borderline". The mechanism is sometimes hackelig, the locking beads come to get out better and sometimes worse, the tolerances appear to be "generous". That worries me, after all I do not want to lose my car keys. Genuine Swiss quality looks mE different. One clutch is for 4 weeks use. So far it is working properly.
