I know it’s a cliche, but the best device for anyone is whatever fits your anatomy. I’m my case, I could slip out of any device, sometimes accidentally in my sleep even, until I stretched my PA to 8g and tried a PA-5000.
That being successful, 6 months ago I was upgraded to a Mousetrap from malechastitynow.com; which I’ve been in continuously except for inspections (handcuffed) for chafing or other problems and sessions (escorted) of laser hair removal. We are confident now on the health and hygiene front. So once the laser sessions are done, the security screw will be fastened with Loktite Red “for the duration”.
