by Kevin Perkins The Shad Mirror mount phone holder 5.5 is simply brilliant. I love it. Easy to fit. The safety strap is a great idea and sets it apart from similar products on the market. Waterproof case is perfect and fits the SAMSUNG GALAXY S6 with room to spare. The supplied shims help take up any extra room. If I could improve this product with one thing it would be a headphone extension cable/socket with a waterproof gland on the side of the case somewhere to pass the cable through.
