Unobtrusive compared to some other holders. Rubber surfaces grip well on car vents and mobile phone without scratching, grips and holds securely. I have an older smaller (narrower) iPhone (6S) and holder bracket holds it OK but less tightly I think than current larger mobile phones (maybe increase spring tension slightly in holder for narrower phones?). Also would be nice if some kind of swivel feature allowed you to rotate the phone facing more towards you, but probably works for 90% of cars if the air vent is close to the steering wheel. Overall a very good product and design I think.

The holder fits well to the air vent, and holds my iPhone securely. Love it!
