BA-34R

My experience

The BA-34R is secured by an inner glans ring that clamps down behind the head of the penis when you attempt to pull out. The glans ring is attached to an insert that sits between the ring and cage part. I dinged this cage for comfort because the insert leaves a small gap at the attachment with the ring, and can pinch during certain movement. I purchased the cage in titanium, which is more expensive, but I think it was worth it. The cage is very lightweight while still being very secure. It uses security screws, which are a bit finnicky and can be easy to lose during removal due to their small size. Overall, I would expect that the BA-34R is one of the more secure chastity devices that does not need to be secured by either a piercing, tetherspout or full waistbelt.
