I got this lock as an upgrade to my conventional lock.  I like that I can use an app to lock and unlock my door, as well as keep track of when the door is locked or unlocked by my family members.  It was easy to install, and the app set up was a breeze.  The app is fairly intuitive, and I really appreciate the upgrade.  The touchsreen is sleek, and works well.  I like that I can give the code to my family to use, without having to make sure they have a key.  I like that I can also choose to not give peope the code, and can instead just unlock the door for them with the app.  Great smart lock.
