Air vent magnetic phone mount for $4

This magnetic phone mount is $4 on Amazon when you use code MHE52LAQ. It's usually $9, but occasionally the price drops to $4.

I started using a magnetic phone mount for my car over a year ago, and I think it is the best way to secure my phone to the dashboard. I've tried lots of other kinds of mounts, and this is the most convenient. The only downside is that you have to apply a thin metal plate to the back of your phone or phone case so it will stick to the the magnet on the mount. But the plate is very thin and it's not a bother.

The magnetic mount attaches to an air vent on your car. This could be another downside, but since I live in Los Angeles, I'm almost always running the air conditioning so it keeps my phone from overheating when the sun is on it. That makes the air vent mount an upside for me. (With other mounts, the phone would get so hot that the safety shutdown would sometimes activate to prevent damage to the phone.)
