Review on 📱 Universal Car Phone Holder - Easy One-Hand Operation, Gravity Auto-Locking System for 3-6 inch Screen Smartphone & Other Devices - Black by Johnathan Delgado

Cellphone turns on and off normally unlike other devices I've tried. Won't stay pressed against the driver's left air vent near the door, but it's fine in the middle. I wonder if the heat from the vent will affect the phone on those particularly cold days. I gave it three stars as it rattles when the phone is not in the unit and I struggled with tiny little screws to attach the stabilizer bar to the back. It never felt like they were going straight, too weird an angle. It has no battery, but the form requires input.
