Holds my Galaxy s20 in place on bumpy road

The suction cup has difficulty holding, especially when encountering bumpy roads in Washington,

and it hold my Iphone 8 just fine on rough roads.

The ram mount itself is nice, but it tends to move in my big rig that bounces a good bit on rough roads.

The gripper arms lack depth and spring tension can not be adjusted for different loads and/or riding over less than perfect roads

Doesn't shake down the road, and is very adjustable

I've driven the lovely roads around Chicago and it hasn't fallen off

I use these in the cab of a race transporter and they have held my phones and tablet in place on the roughest roads

I set it two weeks ago and in that time drove down some bumpy roads and it is still solid on the dash

The rubber feet on the support posts are well made, very durable and hold the phone solidly in place, no matter how rough the road gets

I drive an oil field truck and the mount stands up to every lease road I've drive on so far and believe me it's been on some rough roads.

The mount remains on my windshield, even when driving over bumpy roads.

This causes the phone to shake constantly on bumpy roads

Holds my phone or GPS steady regardless of how rough the road or trail is

Most importantly, you can tighten down the ball joints on the metal arms so tightly, that it has little to no vibration, even going over rough roads in a rough vehicle (like mine).Boom

Previously tried several other brands like iOttie and could not hold up to potholes and rough/rutted roads.

After using this mount on my motorcycle for years, and after going through 3-4 cheap-o suction cup mounts from various local stores, I finally picked this up for my car and couldn't be happier.

While this look rather industrial, it works exactly as you would expect it to.

Ram always makes great products and works exactly as it should.
