Mature Metal discussion

I currently own a Jailbird and am considering ordering another chastity device. I want something slightly more compact. My current JB measures 1 3/8” inside diameter by 2 3/4” cage length. It fits well, allowing me to run and stay active, but I’m seeking a bit tighter restriction. Since I don’t have heavy low hangers, one testicle occasionally slips out, so downsizing my barring is necessary anyway. Therefore, I plan on purchasing a new set. I am looking at 1 1/4” x 2” … possibly 2 1/4” if I choose the Watchful Mistress because it requires that size for side bars. Has anyone had experience with the Watchful Mistress? Did it feel secure? Was cleaning easy? How was the weight and profile? I’d love to hear your thoughts. The larger band on the underside of the penis near the crown intrigues me. I think this could help prevent stimulation.
