We purchased our smart deadbolt on a trip last fall. It has been 100% reliable for both us and our pet sitter. We would love to use the auto locking feature but, having a dog, we would continually be unlocking. We purchased the gold coloured unit and find that it looks elegant and matches our lever handset. The smart deadbolt was a breeze to install and easy!! to set up. I really appreciate the ease of access to the settings and batteries via the large sliding inside face. It's a good feeling to press the lock button and walk away, hearing the "locked beep", not to mention having the flashing red or green (locked/unlocked) light seen from within. I think friends are getting into it -- a recent visitor exited ... and locked himself out!
