I bought this lock thinking it would be easier when coming through the main use door with hands full. It is a great concept, but is slow to respond often times. The app has to be open on your phone to work the lock, not a problem once you get use to it, but then it often times says out of range and you have to pull the phone out anyway. When it does work it takes ten seconds or so to open the lock. It just isn't as functional as it sounds for the price. Maybe it would work better with just the key fob and not using the phone and app.
