Does it mount securely?

Yes. The AMPS plate uses strong VHB adhesive and four screw holes for a tight, non-wobble grip on any flat surface, whether it’s a wall, dash, or console.

Can I adjust it easily?

You can. The 16mm ball joint rotates 360° and tilts smoothly, letting you find the perfect viewing angle while keeping the mount steady during movement.

Is it compatible with all phones?

Yes. It works with any smartphone—iPhone or Android—with or without a case, as long as the holder supports the AMPS 4-hole pattern.

Does it include everything I need to install?

It does. The set comes with the AMPS plate, VHB adhesive tape, and four screws, so you can choose between sticking or drilling for setup.

Will it stay stable while driving?

Yes. The solid metal base minimizes vibration and shaking, keeping your device secure and easy to view even on bumpy roads.
