Review on 📱 360 Degree Rotating Aluminum Alloy Bike Phone Mount | Adjustable Handlebar Phone Holder for Motorcycle, Mountain, Road, Hybrid Bikes | Compatible with iPhone Xs Max X 8 7 6 Plus, Samsung S9 S8 S7 by Luis Adu

I love the overall design of this bike phone mount. It fits my iPhone X in a case. Part of the phone holder works as intended and protects the phone. The rubberized handlebar grips are nice and easy to fit and adjust on a road bike. The fault lies in the attachment of the bank angle adjustment screw. The closure is completely unscrewed very quickly and can then no longer be tightened. I used this unit once and at about 5 miles on a road bike it literally flapped in the wind. The spring washer used to hold the fastener is weak and requires very little pressure to compress. No matter how much torque I used to tighten the screw, it loosened again after a few kilometers. If the manufacturer can make a decision, I will revise this review. June 5, 2020: I am revising the overall rating from 1 star to 3 stars because the seller responded appropriately and received a full refund.
