iv been through a few different chastity devices in the past but could slip out of them all, this design is perfect, the Hinge allowed for a nice snug fit with little chance of my balls escaping, as i do have a fairly tight sack it makes it nearly impossible for most other designs i have tried, but i cannot recommend this design highly enough, the finish on the 40mm Steel Hinged Back Ring is perfection, no sharp edged, i have slept in this for the past few days, walked round with it, have gone swimming, and everything fits snug with little to no intrusive feeling while i go about my daily activities,
I Bought this item Steel HoD S99 to pair with this 40mm Hinged ring and it's a dream, everything fits perfect, no pinching, easy to put on myself or have my partner do it,
cannot highly recommend this site enough, remember sometimes it takes a little trial and error to find that perfect fit, but once you do like i have, im a customer for life now
