So far Princess has kept me locked in one of several steel Chinese cages. For my six-month anniversary locked we're considering a PA piercing and a custom steel device. Because of its low profile and ring-less design, a Lori's #1 looks like it might be best for all around long-term lockup of an active individual. 1. If you have a #1 and are an active runner and/or cyclist what's your experience with it? 2. Is the "key" for the security screw suitable to wear on a necklace or is it an industrial looking tool? 3. We'd consider other steel cages suitable for wearing while running, road and mountain biking; so any suggestions will be appreciated. Thanks for your consideration.
