Question about Quad Lock Case

Why does this product have two different rear views? One with a raised ring and one with a MAG ring. Which is the right one?

Hi, the ones without the MAG are the older versions of the case, I myself had one without MAG, the newer cases have the MAG ring that is also interchangeable in different colours

The one with the MAG ring is magnetic and can also be used with the new brackets, for example I now also have the one with magnets, I need this for the car, it is too unsafe for the motorbike, so without magnets, normal for tightening
