Very easy installation and I love the fact that this helps provide effortless but at the same time high security to our home. I'm the type that loses my keys at the bottom of my purse or sometimes I don't have them at all! I do however carry my phone at all times! Since this lock is compatible and works great with the easy to install, easy to learn simple APP that you download to your phone, I no longer have to worry about either locking or unlocking my front door. The lock works great and it has many options as far as unlocking and locking your door. I have found it be extremely convenient when I'm at work and my parents show up to my house to drop something off. With this lock you don't need to give out multiple keys to friends/family since you can lock/unlock with the APP. It even alerts you if someone comes in or leaves. I highly recommend, one of the best additions to our home security system.
