Greatest Mount System Ever

The two point mount with universal phone holder is great. I will not use it for a phone but will use it for an RV rear camera. This mounting system is absolutely great.

Decievingly Good

When I opened the box the arm seemed to be way too short. Where the amps balls are installed is plastic so I was worried about sturdiness and durability. Went on a 900 mile road trip with an 12” iPad mounted the entire time. The iPad does shake a bit with the motion of the car as you hit bumps but the accessory mount itself didn’t budge from the position I had it at. Coupled with the rubigrid it is my opinion this is the best way to mount accessories. In this case specifically an iPad. I’ll probably pick up a MagSafe mount for my second Amps ball.

This MagSafe attachment holds my iPhone securely even with some vibrations transferred from the truck. Mount used in 2025 Chevy 2500.
