Chastity device discussions and reviews discussion

I’m interested in buying a Gerecke device and like their integrated locking system because my wife finds the padlock gets in the way. I also prefer the cleaner look of a unit without one. Does anyone have experience with these models? Is the lock reliable? My main worry is that if there’s an issue with a standard padlock, you can always use bolt cutters to remove it. But if the integrated lock fails, it might mean an embarrassing trip to the locksmith!
