I have worn these shoes almost every night for my nightly 4 mile walk and after 2 months, I feel like I need a new pair of shoes. So that white piece on the bottom of the front where your phone will sit was out there by us to make his phone tall enough to reach the magnet. The instructions were clear and easy to undertand. The screws and other HW included are wimpy. Otherwise, you you are looking for sports, great quality for music or if you are going to use them a lot, go for a different option but maybe you have to pay more. These work! I work from home and find great value in being able to wander around during long meetings. It was a birthday gift that I have to send back. The USB dongle is about the same size as the one you might have for your wireless mouse or keyboard, so it is small and unobtrusive. Good to know if you are stuck in the house.
