I currently have and I'm locked up in my Holy Trainer. I love it, the issue though in the design is the back over the penis, there's a lip that pushing against my body and especially annoying when working sitting upright.
I find the Holy Trainer much better than my first one which was a CB6000, one of the cheap pins snapped and the ball ring not being round was just a joke.
So I'm looking to drop several hundred dollars a mature metal cage. The one disadvantage is the weight but I enjoy that. I have small balls then recess a lot so with any cage I feel more like a well endowed man that because of the cage is useless to act!
Even though the Holy Trainer has the wide round ball ring I'm concern over skin irritation for the balls and also the penis.
So any thoughts from those who have gone to metal and/or experience with Mature Metal? I also like their padlock free security screw.
