Does not hold as advertised
Color: Black
When the dash got hot from the sun, the glue gave way and everything ended up on the floor. Couldn’t send it back because the time limit had passed but I don’t use it

Best one so far!
Good quality and suction is strong that the mount stays in place on any part of your windshield. Installation is easy and removal of mount is easy. This is one of the best mounts I have used so far.

Strong magnets, good suction, and easy to twist on/off
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.
