I live in a rented apartment in Seattle, WA. I always find it hard to keep track of my unit keys, often forget to carry. Also when my wife enters the house she also needs to carry a separate key. We both work so when the guests come either of us has to return to home to open the door, which is very problamatic. On top of that, my building management was not allowing em to install any smart lock from outside my unit's door that could potentially replace the use of keys losing their access.
So I was looking for a solution that solves my problem and at the same time keeps the same keys usable for the building management. August Smart Lock Pro+ is a life saver for me. All parties are happy. I no longer have to carry keys and allow my guests to enter whenever they arrive, can open the door remotely. Building management also does not have objection with it either.
