Rated 1 out of 5 by from Android app doesn't work We purchased 3 of these directly from Lattis. Lock looks well made, but the android app is not ready for prime time. It functioned properly only for one hour. It won't stay connected to my Galaxy S7 and messes up all other Bluetooth functions. (I had to delete the app to stream music.) We can't the app to even recognize my son's Moto.
