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

What a Cute Egg… Err Flower
Easy to install and easy to use! It’s as simple as turning two knobs to tighten onto the screen and placement of the arm. So adorable and has a strong magnet. Looks a little like an egg but who doesn’t love eggs and daisies?

Good mount for tesla cars
Build The design is a very different when compared to regular magnetic mounts. Some people will like it and others wouldn't. This looks like a daisy flower and can be mounted to any tesla car. Material The phone holder itself seems to be made of good materials, and offers a sturdy mount that remains secure in place. It does take some cranking to tighten and there is always a worry of over tighetening and breaking it. Functionality Installation and removal are straightforward and quick. The magnet provides a strong hold for my Samsung Ultra, and keeps it firmly in position during drives. Value for Money (VFM) At $16, the product offers good value, however at a tad higher price. Would recommend only to those who like the looks and need the mounting functionality.
