The Echo Quick Release is a great little product. It makes it easy to quickly remove and put on your helmet without fumbling with the "D" ring. Echo is the only metal-to-metal locking system, making it very safe. It has exceeded D.O.T. testing standards. You do not have to alter your existing strap on your helmet it works with it so you may remove the Quick Release if you want to. After you get it correctly on your helmet and adjusted to where it should be you do not have to adjust the strap every time it is set just click it in place next time. They come in 7 colors and are also easy to put on and take off while wearing gloves (ex. motorcycle, snowmobile, etc.) They are made in the USA and a great inexpensive accessory to have if you own a helmet.
