Review on Waterproof ROCKBROS Bike Phone Bag with iPhone Xs Max 11 Pro Plus, Samsung S10 Compatibility - Bicycle Front Frame Bag for Convenient and Safe Phone Accessory Storage by Richard Alemayehu

The water resistance has not been verified. Otherwise, the bag was easy to install and barely moved in place, only slightly side to side on the edge closest to the rider. The phone cover allows you to control my iPhone, apart from fingerprint recognition, of course. However, as others have posted, I hit him with my knees while riding. In my case even while sitting. I don't think there's anything wrong with this bag - it can't be much narrower and still fit a phone. I think this concept just doesn't work for people who ride with their knees close to the frame.
