RAM® X-Grip® スマホマウント 1/2インチ径レールベース付き

The X-Grip's rubber arms hold my phone rock-solid even on bumpy gravel roads, and the 1/2" rail base clamps down tight without any wobble. I've had it mounted on my ATV for two weeks of hard riding and haven't had to adjust it once.

Finally got this mounted on my boat's railing and my phone stays locked in place even when I hit some rough water. The rubber arms on the X-Grip holder are surprisingly secure but easy to release one-handed.

I was a little worried the rail base might wobble on my bike, but it clamps on tightly and the X-Grip holds my phone securely even on bumpy roads. The rubber arms flex just enough to grip without scratching.
