Review on WUTEKU Flat Magnetic Cell Phone Holder Kit for Car - Ultimate Compatibility with iPhone XR XS X 8 7 Plus, Galaxy S10 S9 S8 and More - Pro Driver's Choice by John Eaton

This little magnet is INCREDIBLE! The stickiness of both the magnet and the small plate for your phone is very sticky! The plate for your phone is incredibly thin and can fit under a case and of course still be magnetized by that case. I have one for both my cars and I will 100% buy another one when it's time for a new ride. I will never use any phone storage device other than this one. They're all rubbish, but this thing is AWESOME!
