Review on 🚗 Pro-M Magnetic Car Mount Series Metal Plates by Koomus by Geoff Cooper

I have three Koomus magnetic phone holders with a CD compartment. I recently upgraded to a Samsung S9 with the OtterBox protective case. I put a metal plate between the plastic case and the rubber sleeve. Unfortunately, the Koomas plate interferes with the phone's wireless charging. Not sure if the square hole in the plate helps with phone charging, but if you want to use these plates wireless charging isn't an option.
