Didn't Stay Put
It did clip onto the air vent, briefly.  I put it on the back seat air vent, but it dislocated quickly.<br /><br />I also put plenty of essential oil on a cotton ball and placed it in the cavity, but it provided little more air freshening than if I had just placed the essential oil-loaded cotton ball in a cup holder.<br /><br />Altogether disappointed.
