Review on Maxboost Magnetic Car Mount (3-Pack): Universal Dashboard Holder for iPhone 13 12 11 Pro Max XS X SE 8 Plus, Galaxy S21 S20 Ultra, S10, Note, HTC, Pixel, LG, Huawei, Nokia, Moto - Works with Most Cases! by Rich Rickenbaugh

I like that they keep my cell phone in the car. With Tennessee just becoming the hands-free cell phone state, they're perfect for holding my phone so I can see who's calling or my navigation map. They are REALLY strong and sticky 3M stays in place. The metal plate on the back of my phone (between the phone and the cover) connects perfectly with the magnet. Try it. Three magnets come in a package with several metal plates. I have shared them with other family members and they love them too.
