We have played with some devices. Mainly they have been the cb3000 and the cb6000. They both were not secure. And they both broke....split up the seams. I purchased an exobelt device. The exobelt extreme. It is a clam shell device and a scrotum trapping device. After trying some other devices...I can say this is truly and honestly secure. I have been able in the past with cb3000 or 6000 devices to pull out but this device is for real. Day one.
