It is ok
It is decent. Looks like it would work well. It is a little bulky. I bought this one and another one from a different seller. I returned this one due to the thickness of the arm. It was a little bulky. One thing to be mindful of there is no adjustment for the radius of the arm. Depending on how you position it your phone can be quite far away from the screen, it may not bother you, but for me I wanted them as close as possible

Strong Magnet, Great Price!
Mounted in less than 10 seconds. The magnet is super strong and holds the phone through all the bumps the road throws at it. The two thumb screws make for fast angle adjustment. The mount location puts the phone in the perfect spot for viewing without obstructing the view of the road. This phone holder is built well beyond its price point! I will be buying a second one for the wife's Tesla.

Works better than expected. Very good
Color: Black, Color: Black
Very nice fit and finish. Feels very high quality. Phone charges very quickly and doesn’t heat up as much. It charges through my heavy duty case that i thought i would have to replace as it doesn’t charge on other charges that ive tested. Very impressed.
