Rings for Penile Attachment and Locking

I’ve spotted these devices in a few spots; I believe red chili produces some good versions. Essentially, it features a primary ring similar to standard ball traps, plus a secondary smaller ring designed for the shaft that locks into place with the main one. My dimensions fluctuate significantly throughout the day, and since my job requires me to be quite mobile, wearing a full cage can feel a bit clunky. I’m curious if anyone has used these rings before. On days when I don’t have a strong urge to masturbate regardless of whether the cage is on or off, having a ring secured at the base of my cock seems like it would naturally discourage that anyway.

What are your thoughts? Any personal experience with them?

Bumping this up—anyone here?
