The Halo Keypad wi-fi enabled smart lock will definitely bring you peace of mind while in your home, or away from your home.  It was easy for my husband to install, took him like 45 minutes.  The app was very easy to install on my cell phone, I had no trouble installing the app, only took one time to install the app, I followed the setup instructions kept my cellphone close to the smart lock.  There are so many great features, from being able to setup different codes for different people, to even being able to lock your door when your away from your home!  We live in a rural area and it takes about 20 minutes to get to town, once there, I went to the app, and hit lock, and it worked!  I highly recommend this product!
