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 Bryan Brant

Beautiful and very easy to install product. I'm concerned that the reason for the lower star rating is the power of the included magnet. For a standard Apple iPhone case, this can be acceptable, the thickness is 2-3mm. Mine is about 4mm thick and I find the strength of the magnet to be weak as it moves when docked. I ended up having to position the base so that the phone is either flat, which is undesirable, or touching the bottom for support.
