I did not expect this lock to be so simple to set up and install. It really was a breeze with zero complications. I love that it's compatible with all the smart devices that I already own. My friends were shocked when I first came back to my house with them and just touched the lock to go inside. I gave my family members key cards and it makes things so simple, especially when holding groceries. Because it uses the latest tech, it's super small and inconspicuous. This tiny, technologically advanced, yet simple lock is really a must have. I'm thankful that I have it.
