I was so excited when I got this in the mail, I couldnt wait to try it out. It slides in so easily and stays in place too. I have so many great compliments on the cock plug and people ask me all the time, where did you get it? I refer them here. It works great locked onto a cock cage with my cockplug, cock cage and Prince Albert all padlocked together. It is an awesome sight. I just wish the insertable was a little longer.
