Fits snugly onto one of the vent louvers on the dash and stays put.

Pros:- Holds tightly enough to the vent louvers and fits my vertical vents.- Vent-holding pieces do not seem to have scratched my vents

So far the wider of the rubber grab slots seems to work best on my vent louvers and lid on center console pocket.

Excellent product -- soo much better that the previous one I ordered, which kept falling off my vent louvers
