I have a no-name device purchased off eBay that my lover and I are content with for now. I do, however, dislike the movement of the padlock and would like to offer my lover the little bit of extra control of knowing that I can't easily remove the device by breaking the lock. Miss Lori sells this replacement: #510 Secure Locking system for devices that take a padlock. Cost: $125. Does anyone have experience with this?
