What's your opinion on metal belts for men?

I have been considering getting a full metal belt for a while now. The kind that locks around the waist as a belt and has a panel running between the legs for a tube to hold things securely.

I have been doing some reading or articles and reviews, I found opinions ranging from them being the best device ever to them not really fitting the male body well. Many of the good reviews came from sites selling there own devices so I'm not sure how trustworthy they are.

I love the look of them and like the idea of a device that is bigger, feels more substantial. I am hoping there are a few people on here with more/any experience that would be willing to give their opinions.
