Mercedes CLS55 AMG W219, Kreezi RX11 Pro Phone Holder Mount
I wanted another phone holder, as the vent holder I was using looked “messy” and was blocking the vent. After a search, I went with the Kreezi RX11 Pro (whats in a name…) which has a strong suction cup and extendable arm.
It also clamps the phone automatically once you push your phone against the backing plate.
