I didn't expect to add anything to this thread because I use a CD-slot mounted holder that is sufficient. I don't hate it, as my daughter would say.
Then today I was getting an overdue car wash and saw this $10 vent clip magnetic holder at the cash register. Had to have it to give it a try because like the OP, I have wanted something closer to my line of sight and have been too cheap to spring the $60 or so for the ProClip solution.
I pulled over to install it and I gotta say I'm impressed after the first 30 minutes of testing. I used one round magnetic disk which I slipped into the credit card slot of my iphone 7+'s case. The holder also comes with a larger rectangular piece if needed. Both metal pieces come with adhesive backing if you want to attach them to the exterior of the case. I slid mine inside the case and the attachment is nice and strong.
I pressed the base onto the lowest vent fin so that if it drooped it didn't have far to go. No drooping so far. My coiled Griffin lightning charger cord easily reaches. Nice to have an uncluttered view of the center stack again.
Ten bucks for a small upgrade. We'll see how long it lasts.
