I recently changed all the locks and door knobs on my house. I upgraded two of the deadbolts to August locks, and I love them! It took me about half an hour to install both locks including setting them up with the app and replacing the old deadbolt mechanism. Now I can see when my husband has left a door open, and have peace of mind when one of us forgets to lock the deadbolt. I love the notifications that tells me when it auto-locks!
