I'm glad there is some interest in this. I can say from experience that it is very frustrating, and not in a good way, to be unable to find a satisfactory chastity device, particularly after tasting the benefits it can give to a relationship, only to find the device does not really work. If it results in a few more chastity enthusiasts being locked up successfully, I will be very happy. As for progress, I am locked up at the moment and really need to enjoy the benefits and give some other things my attention for a while. Maybe there is someone else out there with both the need for and the ability to make a similar device. If so, let us know what you done.
