My iPhone 8 Plus bounces wildly even on relatively well paved roads.

I’ve had other ones without magnets that have broken while driving due to the heavy otter box case on my phone or crappy products or bumpy roads

The long arm vibrates a little unless you're on a very smooth road.

The readjustable neck is the perfect length, the magnet actually holds the phone, even on bumpy roads and the suction part actually is great after wiping it with water

Arm is very flexible but still very hard to keep phone stabilized on bad road

I would buy again it works perfectly and holds my phone even on bumpy roads

Your phone shakes a little bit if you're driving over rough roads, but the magnets powerful, so no worries of your phone slipping off

It shakes a little bit as you drive in a aggressive Road

Holds securely and no shaking when on rough roads

It’s much better than the last one I had (different brand) but it’s still a little shaky on bad roads and it makes me nervous my phone will fall

The magnet seems to have the perfect amount of strength to hold the phone in place as well as to be able to dismount it when your done

It's never been easier to use my phone while not being totally distracted as I am driving
