The OSOMount is the best vent mount I have tried. Here's a summary of pros/cons:
Pros
+ Stiff clip for mounting on vent (moves less)
+ Open big for easy use on iPhone 6s Plus
+ Large grips so phone stays in place.
Cons
- Ball joint could be stiffer, tends to wobble a little.
- Spring was weaker than I was hoping and could be stronger, but still works well enough to hold phone in place worry free.
In summary, this is about the best vent mount you'll find. The mount itself is good quality and has a good, solid clip mount and great grip. The only thing I would change is a tighter spring and a stiffer ball joints. If you're in the market for a vent mount I would recommend this.
