I wasn't completely sold on the idea of a smart lock but since this only replaced the inner turning mechanism, I figured it was worth a try.

After a few months of use, I will have to say that I only bring out my keys if I pull in to the driveway and end up taking longer to open the door (like bringing in the trash bins). The auto lock/unlock feature is great. We literally just walk out the door and jump in the car and go. Getting the notification that it auto locked and then a second one for going into away mode is just too convenient.

There have been a couple times where the door wasn't shut all the way but the door sensor reminds you that it has been open for awhile. So I am pretty confident that when I leave the house, it is locked down.

Bonus: Our little one always struggled with turning the key to unlock the door. Now he is the first one to the door every time!
