Mophie magsafe car mount doesn't hold
I bought the Mophie charging vent mount with magsafe for my iphone 15 pro max, but it doesn't hold it up at all. I need the adjustable arm and it's as tight as it will go on both ends of it but is still easily moved, so obviously my iphone just flops down. I know it's kind of heavy, but it is listed as compatible with the 15 Pro Max. Is this a faulty unit or do they just suck?
