It's a neat concept, but the app is very inconsistent. It's very convenient if you have the key fob, but trying to unlock with the app is a pain. It either does not recognize the signal or unpairs the lock from your phone. Considering the high price, it seems like this core feature should function reliably. For the money, I expected more. I would recommend waiting until Noke fixes the app or releases a newer version of the lock before purchasing.
