I am very pleased with the function and the design of this magsafe compatable phone holder. The magnets are very strong and will hold securely whether on smooth or rough roads. It rotates easily to conform to whatever angle is needed and works best for your application. The twist on/off suction device is easy to use and can be tightened or loosened with finger tips, you don’t have to give it an eagle claw grip to turn it, and this makes it especially pleasing to my wife.
