Review on Securely Mount Your Smartphone, GPS, or Radio in Your Car with Case Logic Universal Car Mount & Air Vent Adapter by Brad Wall

I do not recommend the air vent mount. When I tried this method, one of the fins on the vent cover broke. The suction cup mount on the window works well; However, the block vibrates a little, and the more, the longer the extension from the attachment point. But you can position it to support it with your hand if you need to see it. The good thing is that it is adjustable for different size phones. If I did it again I would probably give it up.
