My daughter recommended this to me since I was always struggling with purse, packages and keys. Now, I can easily leave knowing with one push of a button my home is secure and a quick entry of my code lets me in regardless of how much I am carrying. Why didn't I do this long ago? I have recommended it to my friends. I have given both of my grown children their own codes so they can enter easily whenever they need to. I added the matching lever handle and my front door looks better than it ever has.
