Review on 📱 Mob Armor Mount Switch - Magnetic Phone Mount for Car - Universal Cell Phone Holder for Vehicles - iPhone & Android Compatible - Large, Black by Michael Olsen

This is a good product but the top price is $30. You must use the adhesive disk that comes with the kit and even then it is not stable vertically (straight up and down). However, it remains stable when installed on my bike's tank without a pressure washer. The goal was to use the windshield, but it has to stay on the bike's tank. As said, it's not designed for vertical use and won't stay upright when vibrated or rotated.
