Chastity device discussions and reviews discussion

Does anyone know of a metal chastity device that’s much like the Holy Trainer V3? The ring dimensions, spacing between cage and ring, how it locks, pointing down, being discreet, and overall comfort make the HTV3 tough to beat. I’m leaning toward getting a metal one, but custom designs can be pricey. That cost makes me pause about investing in something that might not match the HTV3’s comfort or stealth level. Any advice is welcome.

Thanks.
