I have traveled over 20,000 miles using this on my motorcycle. I needed to replace the rubber straps a bunch of times. I had one unit fail, the spring on the slide rusted and broke, but that was from many times being in the weather. I am still using this a my primary phone holder on the motorcycle, i have two mounted on the handlebars of my Harley, one for my phone and one for my wife's phone. I have NEVER lose a phone due to device's failure to hold my phone.
