Review on 🚗 2 Pack Magnetic Phone Car Mount by FLOVEME - Hands-Free Universal Holder for iPhone and Samsung Galaxy - Air Vent Mount for Safe GPS Navigation by James Dominick

These magnets are designed for light phones. I tried using it with the Galaxy S9 and S20 and it didn't stick to the case or the natural metal plate inside the phone. When I attached the included plate to the outside of the phone it held tight, but the entire clip then buckled and eventually fell off when I was wearing a case. I haven't used them since then.
