Review on Gray Air Vent Phone Holder for Car - Miracase Universal Handsfree Mount with Adjustable Clip - Compatible with iPhone XR/XS Max/XS/X/8/8 Plus/7/7 Plus, Galaxy S10/S10 Plus/S9/Note 9 and More by Dink Rivas

This is the best iPhone XS Max mount. It attaches to air vents (a bit silly to be honest), but if you follow the instructions, it works great. My vents are vertical keeping the vents secure and the phone feels very secure. The lugs holding the phone are quite long, which is a good thing. Works with an Incipio case and a business card holder on the back. Probably also works with "pop socket" or "ring". The part that connects to the air vent seems long enough to work with all my vehicles. This is a great idea and design, it holds the phone securely and allows you to connect to the micro USB port at the same time.
