I got the Apple iPhone 12 Pro Max clear case, Caudabe Lucid Clear and Totallee cases. Out of the three I lean towards the Caudabe, but most likely will return both it and Totallee because while Magsafe works (the charging works), there is a major difference between the magnet strength in the stock apple case and the third-party ones (at least at this stage).
I plan to get the Belkin charger and will need a strong magnet hold so, for now, it looks like the stock Apple case.
