TERNENCE Stainless Chastity Device Ergonomic Design Base Ring Male Briefs Spares H240 (1.57 inch / 40mm)

I ordered this one because I needed a smaller one and something that fit a little closer, I was not disappointed. Compared the round ring, the curved one definitely fits a lot better and sits in place. I move around a lot at work so I needed one that was a little tighter on the skin. As with what others say make sure to order a size bigger than what you need if size isn't an issue for you. I got lucky because I ordered a smaller size and got an even smaller one than expected, but i needed something extra small so it worked out for me but I imagine that's not usually the case. The pictures are the medium ring size for the larger one and the smallest size for the curved one.

Poorly machined, would not fit with the rest of the device.

overall great product. the last bit when trying to get the lock thru is tough. I found that works for me is kinda like pushing the bottom of the cage down and out if that makes sense. I lay on my back and push against myself (hands on the nub part of cage and then jiggle the lock up and down and that seems to work. it takes some finesse so I'd try it with the cage off first to get a feel for it before trying with cage on. if you get the lock stuck in the first 2 parts also no worries, just push the cage towards your body and itll come right out

One single nut doesn't fit through without some major squeezing but seems like the right size to keep everything secure but would be too hard to put on. Maybe measure around one of your nuts before buying. I have all 3 rings and it's still not a usable secure cage.

When I ordered this ring for my cage I was disheartened when the lock grooves didn't match up at all. I contacted the company via email (the one on the card that comes with the product) and they got back to me very fast. All it took was a little muscle and instruction from them and I was able to get it to line up and it seems to be working perfectly.

Like many other buyers, mine does not fit their other products. The pin holes are too far apart and the 2 pieces where the lock goes are much too tall, or long, to line up with the piece on the cage. I do not see a refund option so buyer beware, you very likely will be wasting your money.

I ordered a cage from this company that is essentially a nub bird cage. They call it the D240 I believe. That is great quality, but only comes with one ring size. So I ordered there newly designed ergonomic rings in all three sizes to have the option. I received this one 1.77 inch one today and was disappointed with the quality. These pictures show clearly that there are burn marks and scuffs. Additionally the weld underneath the locking mechanism is very rough and will likely cause irritation. Hopefully the other two rings are better quality. Overall I’m impressed with the quality for the price point, but still unsatisfied.

I see a lot of post about the rings not fitting the post, it took me 3 seconds with players to adjust them to fit perfectly. The ergonomic style has made a big difference, the regular rings would Would rub my skin raw, this one has not no problems what so ever
