I've played with so-called ball-trap devices for a long time but anatomically they just do not stay on - not just "I can escape" but that within a short while, the device will come off on its own. It rather ruins the effect. I finally put in an order for a neosteel hip belt. Since I just ordered it, the ratio of days remaining to anticipation is at its worst. I'm a loner so hopefully you all are willing to click my requirement links on Carlilock once I receive it and break it in to the point of being able to wear it for longer periods of time. Is there an appropriate forum? Or should it just go in the signature block? We'll see if I can still ride a bike even a little way once it is on.
