  • Nice locker. Just take into account it has a Bluetooth connection with a separate gateway to connect by wi-fi.

    It's so easy to use and the long lifespan ensures that I won't have to replace it anytime soon.

    Jeffrey Wong
  • This S171 fingerprint smart lock is a game-changer! It was incredibly easy to install and looks absolutely sleek with its elegant design.

    The fingerprint recognition is super fast and accurate, and I love that it has multiple ways to unlock, including a backup key option.

  • Originally, I only purchased the S1. The product is great, and then check out this gateway.

    It can have remote control function, so immediately purchasing one with the door lock is very convenient. Even if I am on vacation, I can also open the door to colleagues.
