If you're anyone like me you hate stuff in your pockets. I live an active lifestyle by the beach and love the fact that I can run out the door and not have to look for my keys or have to load my pocket up with anything extra. I can go for a run without having to be bothered by it bouncing around. Also when someone shows up and I'm not home yet I can send them an ekey and let them in so they don't have to wait outside. LOVE LOVE LOVE my Kevo!!!
