This mount looks good mounted on my KIA Stinger’s center vent. It allows for the vent to cool both the phone and the cabin, while not looking like it’s out of place. The mounting is secure, and I don’t worry about my phone falling while driving be cause the magnet is very strong. The vent mounting bracket looks like it belongs in the car. An inexpensive alternative to using mounts with 3M tape.
