The setup for this smart lock was simple to install and connect with the app. I love that you have the option to use the key or the code. The code is great for giving it to my teenagers to access the house and not having to worry about them losing the keys. It also shows me through the app when it is accessed so I know what time they get home. Or say I need someone to come over to check on my pets I can simply unlock it through the app for them. It also tells you the unsuccessful attempts that have been made. The overall finish gives my front door an updated sophisticated look. This lock is definitely worth it with so many features and a peace of mind.
