It was easy to install, software updates made it very stable and reliable, and it's so easy to use that me and my wide simply forget that it's there. It's just part of our daily routine. When we traveled last year for vacation and suspected that one of our pets could have been left locked in our closet the feature that allows to send remote keys was amazing. We just called a neighbor, sent her a key and in a few minutes she was inside our home. After she left, the key was automatically revoked. I cannot compare with other products alike, but Kevo really delivers what it promises. We all use iOS smartphones at home, so the lack of an app for Android isn't a problem at all to us.
