The lock had the same functionality as its predecessors, but made so much better. It’s smaller, smarter and the components are made a smart way finally ( I’ve had to replace my deadbolt adapters many times with generation 2 and 3). Manually unlocking it is smoother and the built in WiFi is so much better than having the WiFi adapter. Only issue I had is that the lock does not come with new screws. The WiFi lock needs longer screws than the screws the older locks used previously. So receiving the lock, not being able to install it, then having to wait for the new screws to arrive that you bought was quite annoying. But all-in-all I’m very impressed and love the WiFi August lock.
