It's easy to install and set up. The instructions are easy to understand and the fact that I can lock and unlock with my phone is absolutely amazing!  Love that you can check all the times it has been locked and unlocked. This can also be used either over wifi through the app, an actual key or turn the deadbolt from the inside to unlock. You can enable access codes for others to enter the home and the App will notify you of any activity.  I like the fact that you can have 250 codes and can easily keep track of them with the app. I also love that it still has the traditional key option as well. Absolutely love the rekey feature.
