It is difficult to install on the vent fins

This fits in between the vent fins perfectly, and allows me to keep the phone in an accessible spot

With the significant weight increase if the iPhone X, plus a case, I'm constantly worried that the clip will fall off, or worse, break my vent fin

I was looking for a cell phone mount that would fit in the air vents of my 2002 BMW E39 M5, which does not have too much space in between the vent fins
