My lock had actually just started to malfunction when I received the August Wifi smart lock. 

Automation: As an apple homekit user my review will be geared towards the homekit side. I love the fact that I can check the lock status from work or home. I now simply ask my watch to lock or unlock the door as I'm leaving or coming home. And it works seamlessly with my automatons for when the last person leaves to lock the door.

Quality: Initially I felt like the lock looked odd from the inside. But I quickly came to appreciate how simple it is to lock and unlock. It feels much more solid and fluid than even my door handle. 

Overall I was fortunate I received this lock as a beta test. And I have absolutely loved it since I received it. I love the fact that when I tell siri good night I can hear the front door lock if I forgot to lock it.
