Review on 📱 ANPULES Wireless Car Charger: Fast Charging Phone Holder for iPhone & Samsung Galaxy - Auto Clamping, Air Vent Mount by Matthew Miles

For my S21 Ultra, this mount doesn't work when used with the extended arm. The problem is that the weight of the phone causes the clamp itself to rotate 360 when I make the turn, causing the entire stand to fall to the floor of the car. If I remove the extension cord and just attach the phone to the clamp, it works fine. If there is a way to reduce clamp rotation, an extended arm could be used, but I don't know how. My pictures show what works and what doesn't with the S21 Ultra.
