The verdict

Why it scored a 77

At $189.99, the August Wi-Fi Smart Lock is the renter's pick: it fits over the inside of an existing deadbolt in about ten minutes, so the exterior stays untouched and the old keys keep working. Quality scores 80 and Features 80 for built-in Wi-Fi, auto-unlock on arrival, DoorSense open-closed detection, and Alexa, Google, Apple HomeKit, and SmartThings support. Value sits at 74 because there is no keypad in the box, and 10,700 ratings recur on CR123 battery life and occasional Wi-Fi drops. Warranty drags at 55 with one year. It suits a renter or HomeKit user who cannot change the outside of the door.
