Christopher Z. ★★★★★

I was a little worried the 11mm bolt hole wouldn’t match my bike’s setup, but it fit perfectly with the included diamond base adapter. The whole thing feels rock-solid on rough roads, and the ball mount adjusts easily without any tools. Exactly what I needed for a secure phone holder.

David C. ★★★★☆

The double socket arm has zero wobble once you tighten it down, which is exactly what I needed for my bike’s handlebar. The 11mm hole fit my existing bolt without any extra shims, though the diamond base is a bit bulkier than I’d like under the mount. Still, solid and secure for the price.

Avery ★★★★☆

The 11mm bolt hole lined up perfectly with my existing hardware, so installation took under five minutes. The double socket arm holds my phone steady even on gravel roads, though I wish the diamond base adapter came with a wrench for tightening.
