Great to have 3 powerful suction cups. I have mounted this on exterior areas of my car going about 80+ MPH on the road with the only issues being the wind drag starts to tilt the camera and may affect your shots. My car has a lot of curves and sometimes the 3rd suction cup doesn’t always become secured, which is likely okay, but doesn’t provide the greatest confidence on the road even for a short period of time. If the center base had more adjustability, that would be perfect to get all 3 to hold to the car surface. The adjustability of every little section provides many options for various equipment to be mounted in many different location
