Great simple little lock that allows you to reuse the key. Set up several of theses and all are simple to set up. The first one did took 45 minutes, but the rest about 20 minutes each. After three months using it, no major 
 issue. The app is east to use. Connects to home kit and other smart hubs with the connector hub. That's the only down side is the need of the connector hub. Another device needing a wall outlet.
