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.
