Review on UbiGear Universal Car Cell Smartphone Magnetic Fast Swift-Snap Wallet Vent-Clip Holder Mount with RFID Blocking - 2 in 1 Credit Card Case, 360° Degree Cradle Design to Prevent ID Theft by Doug Hawkins

Great product. The clip has two settings depending on the thickness of the air vent. I've found it works better in my car than it does in my van. I think it's more the ventilation grilles. The van sipes drop at an angle, making it difficult to maintain a consistent clamp. Luckily the end of the magnet can be adjusted to stop at an angle and in most cases it all works. If you repeatedly pull the phone away from the magnet and then put it back on, the clip will eventually lose its grip on the pole. I wish there was a dash mount in my van too.
