Review on eSamcore Cell Phone Magnet Sticker: Wireless Charging & Magnetic Mount for Car – Soft Plate & Vent Clip Compatible with Samsung Galaxy iPhone by David Miller

I was looking for a phone holder that would really hold my phone and broke after a few days. I have a Galaxy S21 Ultra with an Otterbox case (which I hate but won't buy another case yet). I've read reviews that said it didn't work with the protective case, but if you cut off part of the metal tag and put it over the solenoid, you're fine. I placed the metal next to the camera and I can still charge my phone wirelessly and it still holds my phone in place.
