Review on 📱 Efficient Air Vent Car Phone Mount: Convenient Cell Phone Holder for Vehicle Jeep Truck - Compatible with iPhone XR XS MAX 8 7 6 5, Galaxy Note S10 S9 S8 S7 S6, Pixel 3 2 - Black by Andrew Frison

I bought 2 of these. One works fine. The design of the side wings, which can be closed to hold the phone and released with a small switch, is theoretically good. Unfortunately, one of the two phone holders stopped working after just a month. The side zippers no longer open or close. They hold the vents in place well, but in a car the vents adjust from side to side and when fitted it wobbles around corners due to the weight. I'll try a different one next time and hopefully the attachment feature is more versatile.
