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 James Hounds

I bought this Rock Bros bag from a new e-bike last summer. It holds a lot of gear and is great for seeing my iPhone X while I drive. Taking an iPhone out of a case is tricky - I've often come close to dropping the phone while struggling with the Velcro. But my real problem is the zipper - it has come undone and the bag won't close except with small elastic drawstrings. But it's definitely not waterproof and I can't get a warranty response from Rock Bros.
