By make and model
The Kenu Airframe attaches a phone to a car's air vent, within easy reach of the driver.
The Airframe can clip in portrait mode.
The mount occupies very little space.
The bracket expands wide enough to hold an iPhone 5 or Samsung Galaxy S5.
At less than an ounce, the Airframe is easy to put in a pocket.
The design is simple, although the bracket and grip are too stiff for easy adjustment.
The Airframe costs $24.99 in the US Apple store, and £19.99 in the UK Apple store.
