My wife recieved her new cage for me, a Lori 2a with anti pull out ring yesterday. Never seen her so excited before. She took off my other cage and locked the Lori on me. Fit like a glove. I think the pull out ring really isnt needed but she wanted it included to discourage any attempts by me to pull it out. I dont think its posdible to pull out especially with the ring in there. One more month and it will be 1 yr locked. My wife has told me before that being locked up is going to be permanent. With this latest purchase, I believe her. As far as function this cage is high quality. Its very secure, this one could actually be escape proof. No way to get to security screw, it is recessed deeply. It looks like if you could get to it you would end up stripping the head and then it would never come out....not telling my wife just incase, she might want to do that so it never comes off. Price was good and totally custom fitted. Good cage thats very affordable. My penis is totally trapped and out of my control.
