This was a joke. Claims that were 5 strong magnets to secure your phone. Out of the box I attached my phone on the 5 strong magnets using the supplied metal disc. I shook the holder slightly, phone fell off the 5 strong magnets. Put the holder in the center vent of my SUV and attached the phone. Slowed down to 15 MPH to go over a speed hump on my street. Phone fell off the 5 strong magnets and bounced around the passenger side floorboard. Don't waste your money on this.
