Hasn't fallen yet with a few aggressive turns and accelerate. Obviously if I really tried It will. But when I want to grab and go, it works great.
Also if you've never used gaffers tape before, it's the best thing since sliced bread. Blows duct-tape out of the water. It's mostly used on film and video sets, but if you look you can find it.
Not doubting it's effectiveness, but I am not sticking anything to my phone just to hold it up in front of me in the car. lol
