Just insert your phone into the holder. The phone automatically locks and is held securely in a stable triangular construction. Keep your phone safe, even on speed bumps or bumpy roads, easily from one source. It is super convenient and guarantees safety while driving. The three arms form a triple corner that firmly locks the phone and prevents it from moving when you suddenly brake or drive on an uneven road. The soft silicone pads on the phone arms also protect the phone from scratches. Made of aluminum alloy which keeps the phone more stable and not easily deformed. If you reserve the charging port on the bottom of the mobile phone holder, you can connect the charging cable to the phone even when it is connected to the holder. If you mount this bracket on your vehicle, you don't have to worry about it turning off. Very easy to install and remove. It is not necessary to pull out the entire ventilation opening. Move the vent until it comes out a bit. Then insert the holder between the vents and push them back.
