Customer Reviews (4.8 / 5 · 5 reviews)

Alexander ★★★★★

The double-sided adhesive pad on this base sticks incredibly well to my textured dashboard, and the 2.5" ball fits snugly into my arm. I prepped the surface with the included alcohol wipe first, and nothing has budged even on bumpy roads.

Edward ★★★★★

The included alcohol prep pad made surface prep foolproof, and the adhesive has held my phone mount steady through bumpy roads for weeks now.

Nicholas P. ★★★★★

The 2.5" ball base locks into my double socket arm with zero wobble, and the adhesive pad gripped my dash firmly after just a few minutes of pressure. The included prep pad made the surface ready in seconds, so installation took me less than five minutes total.
