Professional reviewers position the Sifely keyless fingerprint lock as a budget-friendly, easy-install option with strong suitability for indoor, family, and light exterior use. They caution against relying on it in consistently harsh outdoor conditions or for users with very high-moisture or dirt-prone environments, noting that fingerprint reliability under wet conditions is less stable than higher-end competitors.
Everyday users tend to rate this lock highly for interior use and protected entry doors, praising its ease of installation and value for money. The main caveats reported by consumers are conditional grip on fingerprint recognition when hands are wet or dirty, and the need for a gateway to enable full remote features.
