Customers say
Customers find the smart lock easy to install and set up, with clear video quality and an accurate fingerprint reader that can accommodate multiple fingerprints. They appreciate that there are no monthly fees, and one customer mentions the lock locks and unlocks very quickly. The functionality and camera quality receive mixed feedback – while some say it works well, others report it doesn’t work half the time, and while some find the construction solid, others describe it as unreliable. Battery life is also mixed, with some reporting it lasts a full year with normal usage while others find it drains quickly.
