As much as I love the pattern, the functionality could use improvement. The magnet is strong and great, but the fact that the inner ring doesn't rotate easily is the only thing i don't like about this, and it has unfortunately brought the star rating down by 2 for me. In order to rotate the ring the whole thing rotates (and not easily) and it scratches your case underneath the ring.
It pops off and on if I want to switch accessories and with there being so many designs with all the accessories for each design is great. . . I have the white oral pattern and grip ring and if just slides off if I want to put the wallet on or the battery pack and then I just put the grip ring back on
