Review on YOSH Magnetic Car Phone Mount 2-Pack: Universal Holder for Car, 360° Rotation, iPhone 11 Pro Max, Samsung S21, Pixel, & More by Johnny Spencer

This is a very effective magnetic cell phone holder for air vent. This is my first heater holder. EXTREMELY strong magnet requires you to learn the technique of sliding or prying the phone off the holder without pulling the holder out of the opening! Yes, the magnetic field is so strong that the yosh holder wants to stay on the phone. A simple trick is to either slide the phone or pry it at an angle. don't hang up immediately. The mobile phone does not slip off due to the strong magnetic field. The Yosh mount looks very well made, with a nice soft protective coating over the hard internal materials. There are no moving or rotating parts to loosen or break. The price is very reasonable for such a pair.
