This lock was a little more involved to set up with the app (which is why I gave it only 4 stars), but the instructions within the app walk you through installation and set up. I’ve had Kwikset locks that were Bluetooth operated and the WiFi is so much better. More reactive and the fact that you can set individual codes and operate remotely is a big plus. I also like that the keypad stays dark when not in use. The one thing I’m not sure about is having multiple locks work on the same app.
