Query: Use It, Trust It

D-Ring helmet fastners are a pain in the ____s to use. I sent away for three different speed clip devices and the Powermadd Speed Clip was the easiest to install, the one that needed the least re-adjustment once installed, and, having used two of them on two different helmets over the last three years, I can truthfully say they've never come undone on their own and I've never had a malfunction. A lot of motorcycle store Neanderthals say that the speed clips will come loose in a crash. Bull__t. I'm a strong, healthy guy and I can't pull the Powermadd clip apart once latched. And if clip or latch strap fasteners aren't safe, why would a premier motorcycle helmet manufacturer like Nolan use one? It was the latch on my full-face modular Nolan helmet that led me to finding and using the Powermadd device on my other helmets.
