Are you looking for a steel device?

If you are in the market for a steel device, I have this one and it's pretty effective. To each, their own and I prefer the idea of steel. What I personally like about it is that unlike plastic you know you can't just break it off. I also like that you can't cut the lock off it's hidden inside the steel. This says it's on sale this weekend or until they run out. We paid a lot more for the one I am wearing but got some extras with it. I really need to add an update this weekend it's been a while. Haven't been here for a while but I ran across this.
