I received a Baseus 360 degree magnetic mobile phone mount for my car today. It clips on the air vent and has a magnet that holds your phone in place with the supplied metal plate. The mount itself is much better quality than I expected. The spring is very strong, there's no way it's falling off my air vent, even under the weight of my iphone 6. The vent itself actually moved, but I was able to turn my vent vertical so it didn't move down.
The mount comes with two metal plates, one round and one square. It also comes with adhesives so you can attach them to your phone. I opted to put one of the metal plates between my case and phone, so no sticky adhesive was needed. The second plate can be used on another device, or for future use if you lose your first one. The magnet on the mount is very strong. I drove my car over big bumps and the phone stayed in place.
The mount comes in a nice plastic box, which makes the mount look much more expensive than it is. I have been looking at mounts and a mount made specially for my vehicle cost almost $100. This one came in at $8.73, shipping included. For the quality, this price can't be beat. Considering the packaging and quality of the mount, this would make an excellent gift for anyone who uses their phone for navigation, music, or hands free calls.
I recommend this mount and consider it the best bang for your buck.
