I was in search of a durable car cell phone holder after purchasing my new Oneplus. I depend on my phone to get directions all the time, this gravity phone holder is way better. It clamps securely to my AC vents on my RV, my wife's Toyota and my Suburban. There is a minimum of vibration when traveling, so the directions are easy to see. The clamp is very secure so I don't have to worry about it falling down to the floorboard while driving. It is easy to adjust, so I can see my phone easily when driving. The best part is I can remove my phone with one hand by just lifting up on it. I have been very pleased with this product and would highly recommend to others.
