I asked for this as a gift and when I received it, I was excited to install it. The directions were clear and I was able to use the existing holes in my door. 
The setup was clear and I had the lock working quickly. 
But then, that's when the troubles began. I left my phone and key fob inside and as I left I must have brushed up against the lock and it locked me outside. Since my device was inside it would not unlock the door. 
Then the KĒVO software on my iPhone was upgraded. I used to have my Kevo app closed to operate my door, now it HAS to be launched on my iPhone to work. As a result, my iPhone battery life is diminished. The app for me was working fine, why was such a change made?
So until these bugs get worked out, and the product is really close, I would hold off on recommending this lock at this time.
