This mounting system is awesome, but it does lean toward the heavier side and when my phone is holstered it gets worse. However the XL Universal holder fits my Otterbox covered Samsung galaxy s21 ultra.
JK/JKU Universal Dual Ball Phone and Camera Mount (2011-2018) Review
We are happy with the phone mount but not so happy with the camera mount. The camera is too far away from the windshield in this configuration and you get more hood than road when using your action cam. Our suggestion is to not buy this mount if you are concerned about seeing the road clearly in your videos.
