Pulling out is no problem, which device will not let me back

[riverman21]

I am looking for first hand account of devices or devices with modifcations that will not let me back in. Its clear that trapped ball devices are always possible to pullout of without a piecing (I have no interest in a piercing). What I do want is a method that will either not let me back in, or if it does makes it apparent to my KH. Basically I want a method of wearing a belt that if I pullout I either can't get back in or my kh is somehow tipped off. I own the cb6000.

Any suggestions?

The mature metal devices will make reentry extremely difficult if fitted correctly. I can escape mine, but cannot reenter it ... maturemetal.com
