RevZilla Store asked: Why did you choose this?
Edward M: Fits under mirror connection. Gives great flexibility with mounting any of the Ram Mounts. This system really works well, but make certain when getting started that you are ordering the right sizes among options, as it can be a bit confusing at first. The folks at RevZilla are great, but I got bad info when calling Ram Mounts and ordered a wrong size that cost more to return on another site than to just replace. Jul 16, 2014

Kristed S: It depends on where you want the ball mounted. I have the mirror mount and I attach my camera to it - coming off the mirror it is a quick reach of my left hand to control the camera Mar 16, 2014

Edward H: When a bolt is critical and requiring a lot of torque I would not use the RAM ball. Also this allows mounting to a stud. Mar 29, 2014
