Customer feedback highlights ease of app use, straightforward installation and fast fingerprint recognition, but also reports mixed reliability, fingerprint performance, auto-lock behavior and Wi-Fi connection stability. Battery life is a notable concern, with some customers reporting replacement needs after about six weeks, contrasting with the maker's roughly eight-month estimate. For buyers relying on remote access or fingerprint entry, these reports make connectivity and backup access worth considering. The feedback is mixed rather than a guarantee of how an individual lock will perform.

Negative themes

Some customers report battery replacements after about six weeks, well short of the maker's roughly eight-month estimate.

Mixed feedback
