We love having the August Smart Lock. My favorite feature is the Auto Unlock as we pull into the driveway, and auto lock any time we shut the door. We also have the keypad, which makes it impossible to get locked out with options to unlock (phone app, keypad, actual key). It’s easy to install...just replaces the backside of your deadbolt. Probably took 30-45 minutes. It does make a pretty loud noise every time it locks and unlocks, but we are just used to it by now, and I’m not sure that’s true for everyone who has it. Might just be our door. Definitely recommend this lock though! Makes life easy.
