I really liked the concept. I travel a lot and liked the idea of being able to use smart keys if I needed a friend to check on my place... unfortunately too many problems. The lock worked fine at first and then it started to lock on its own whenever the door would close... almost locked myself out when I stepped outside a few times. I contacted customer service to disable to "auto lock" feature. Puzzled they told me there wasn't an auto lock feature. They suggested I put tape on some wires inside. The problem persisted, so I eventually took the lock back and exchanged it for a new one. About a month later the new one starts doing the same thing all the time. I eventually had enough and retired the lock. This was in 2015, so maybe they have it working better now, but I'm not ready to try it again.
