ToughTested Tough Grip カップホルダー タブレット＆スマホマウント

That adjustable multi-pivot arm was the selling point for me, and it actually holds my phone steady over bumpy roads without drooping. The cup holder base expands tight enough that it doesn't wobble, even in my truck's oversized cup wells.

My 12.9-inch iPad fits securely, and the expandable base grips tightly in my truck's cup holder—no wobbling even on bumpy roads.

The multi-pivot arm actually stays put on bumpy roads, which I didn't expect from a cup holder mount. My 12.5-inch tablet fits fine and the 360 rotation makes it easy to switch between maps and a movie for the kids.
