    Missing fingerprint scanner

    This would have been a 5 star review if it had the biometric access as it says in the title description. After installing the lock and setting it up I noticed there's no fingerprint scanner. Pretty bummed about that since it's one of the main features I was looking forward to trying. Otherwise it's easy to install, setup, and use.
