I absolutely LOVE this smart lock! It came in attractive packaging with VERY clear step by step instructions and videos via the app. I was a little nervous at first since I’m not super handy but I was able to uninstall my old lock and install this one super easy from the pictures and videos. The app is very user friendly and I’m able to set different codes for different people - dog walker, nanny, neighbor, kids, air bnb guests. It lets me know if my door is locked or unlocked and I can control it from the app. I am able to see who came and went from the home and what times. It really is a game changer for peace of mind. I will be buying one for all my rentals.. so much easier than physically changing locks! 
I received this product free in exchange for an honest review.
