The dimensions given were quite a bit off with the middle rings being closer to 1.75 inches making them hang loose on me
This product was just as we imagined. Worked well for me given I am on the larger side, I felt very resticted, although was still able to have throbbing erction with it on. Had to feed my dick through it while flaccid to get it on though. We attached a leash to the end d-ring, and had a little play, then she let me try inserting it, she liked the feeling of the rings when I was just going in and out a little way - the metal against the opening of her vagina was very pleasant for her. However, full insertion was all just a bit bothersome and didnt really work as we had forseen.
