A must-have for every door. Not just for tech enthusiasts.

As expected. This is my second lock, and everyone in the family already has one. Easy peasy to install and works perfectly. And the battery lasts forever 😉

Lovely without a bunch of keys

The lock works fine. Sometimes I have to press a clicker several times before it connects.

Good device but still needs some improvement

Generally works well, only the GPS based access from >200 meters often does not work.
