Complete garbage, dont waste your money. Had the unit less than 2 months and cables are falling apart. Battery life is really bad. UGH. Not sure whether it is easy to clean. Maybe some people are using the included wall anchors??? I would never attach a bike hook with anchors - too risky - especially if you have a heavy walmart bike - drill directly into the stud or you will regret it. After wearing for awhile it was as if the slippers conformed to my foot. Definitely 5-stars! Crocs has such a weird way of measuring sizes. It was honestly really easy to install.
