Review on 🚲 AONKEY Universal Bike Phone Mount: 360° Rotatable Holder for Bike, Silicone Motorcycle Mount Compatible with iPhone 11/Pro/Xs Max/XS XR X/6S/7/8 Plus, Samsung S20/S10/S9, 4.0"-6.5" Phones by Dave Hersma

It can be rotated and used on the side of the handlebar stem and as a handlebar mount. The rubber on all 4 corners is durable and easy to put on and take off for the phone (5c). Each of these will vibrate and smack the phone a bit if you're not careful to set it up and add some foam to soften the phone. Adding a small amount of foam (glued or glued to the mount) cushions the phone significantly, stabilizing the whole thing, making it easier to read and keeping it from direct contact with the stem or handlebars. And also on rough roads or wooden plank paths etc. the addition of foam reduces the wobble by 99%
