This item was provided by Uber Eats headquarters when I was in Australia. I was using the same item that I received from someone else, so I have never used this one. It is unused. It can accommodate smartphones up to 6.5 inches. It has many features such as waterproof, sunshade, and 360-degree rotation, and its yellow color makes it highly visible, which is a safety feature. Thank you. Bicycle Smartphone holder Mobile phone holder Top tube bag, frame bag, sunshade, waterproof, dustproof, 360-degree rotation, shockproof, bike, road bike, scooter
