Review on Versatile Aluminum Alloy Bike Phone Mount with 360° Rotation for iPhone Xs Max X 8 7 Plus Samsung S9 S8 S7 - Ideal for Mountain Road Hybrid Bikes by Charles Julian

Works and looks good. You just have to tighten it well enough or the vibration will loosen the screw clamp on a long ride. Specially designed for driving on bridges made of wooden planks that cross riverbeds. It comes with some self-adhesive rubber pads to attach, but they peel off and get lost pretty quickly, so I use it with my phone without them. I have a Galaxy S8 Active and it has a solid aluminum body and a shatterproof screen so I can screw it on pretty tight without spacers. I wouldn't recommend using it on a peripheral phone. As long as you have a protective case to tighten it, you're good to go.
