RAM® X-Grip® 大型手機支架 附RAM® Tough-Ball™ M6-1 x 6mm底座

The ball-and-socket base locks down with zero wiggle once you tighten it, and the spring-loaded grip stretched wide enough for my chunky otterbox case without a fight. I've had it on my bike for a month of rough gravel rides and it hasn't budged a millimeter.

I was a little worried about the M6 bolt size, but it threaded perfectly into my existing mount. The ball-and-socket base lets me tilt my phone just right to cut glare on sunny days.

The rubber grip arms hold my big phone securely even on bumpy roads, and the ball-and-socket joint stays put once tightened. Installation was straightforward with the included hardware, and it feels solid enough for daily use.
