Review on 🚲 Bicycle & Motorcycle Phone Mount, Universal Bike Handlebar Phone Holder - iPhone X XR Xs 7s 8 Plus, Samsung S9/ Note5 Compatible (Aluminum Alloy, Adjustable, 1PCS) by Alexandra Baker

I bought four of these and what a pain in the ass they were: never tight enough to stay stable and solid; and the "button" to put on became very difficult as it cut in and hurt the thumb and forefinger - and even then the damn thing was never tight enough to stay in place. I think the idea is to just switch from bike to bike - good luck with that! WASTE OF MONEY!
