DO NOT WASTE YOUR MONEY! 
 I PURCHASED THIS LOCK AND THERE IS NO PROBLEM WITH THE LOCK ITSELF ITS '''THE APP''' THAT MANAGE THE LOCK SO WHATS THE POINT OF ME USING THE LOCK ESPECIALLY WHEN I ONLY USE IT FOR THE KEY PAD AKA CODES!!! RIDICULOUS TAKE THIS LOCK OFF THE STORE SHELVES DONT BELIEVE ME GO ON IPHONE APP STORE AND LOOK AT ALL THE BAD REVIEWS INCLUDING MINE!
