I couldn't pull this thing off my door fast enough. The vast majority of times, it would simply not work at all when I touched the deadbolt ring. I had Kwikset replace the thing 3 times, none of which helped at all. I returned it and waited for August, which is much more usable.
I still find none of the Bluetooth deadbolt systems are fully reliable. August comes the closest so far, but there are still times I will approach the door and it doesn't unlock, or times I go to lock the door and the app won't communicate with the lock.
