You need patience with mobile phone giant O2's branded holder, because you have to be quite precise when clipping it to the vent. Care is needed when removing it, too, as once it's positioned, the clip locks into place and it's fiddly to take off again. Still, it's well built and decently padded. We would have liked a firmer grip, though, along with a support at the base, as the phone moved when we drove over rough road surfaces.
