Review on 📱 Magnetic Car Mount Phone Holder with Extendable Telescopic Arm, 1Zero Hands-Free Windshield Dashboard Cell Phone Mount for Car - Compatible with iPhone and Smartphones, Secure Sticky Suction Cup, Enhanced with 6 Powerful Magnets by Jerry Chembola

The best I've ever tried. I drive a dump truck, so it's always bouncing and there's a lot of bumps. This is the only mount that can hold my iPhone X. I covered the magnet on the plastic part of my otter case with the rubber part so you can't see it. Even with the rubber between the magnet and the mount, it still sticks to the mount strong enough that the phone doesn't fall off, even when I hit hidden bumps and nearly bang my head on the truck's ceiling. If you need a powerful mount, this is it.
