I do not have a car clip to hold my cellphone. If I had one, my husband would just pull it off because he doesn't like accessories inside our car. It just irritates his eyes when he sees those clips.
For times when I have to check my map or GPS, instead of a clipper, I used rubber bands to hold my cellphone. I slipped the rubber band inside the air conditioner vent near the steering wheel. Then I insert my phone inside the rubber band. That's it, easy and simple, and smarter than my husband!
A hair elastic would be more invisible and probably last longer than a rubber.band. that said, genius idea!
