The noisiest lock I’ve ever encountered, but it does what it says it will do. Works ok with Apple HomeKit, but not as good as other Bluetooth locks, like the Schlage Sense. Great for a rental as it just sticks to the door without needing to screw anything in. The included door sensor is more miss than hit, but it also is still in beta, so that’s to be expected. Overall it’s a handy lock for renters with a lot of great features, but not at all quiet.
