Score: 78/100
Sifely Fingerprint Smart Deadbolt
Score: 75/100Rankings
The eufy Smart Lock C33 is a keyless deadbolt featuring integrated Wi-Fi and adaptive biometric fingerprint recognition. It offers easy installation and long battery life with AA batteries, making it ideal for rentals and garages. However, it has lower security ratings (Grade 3) and lacks advanced smart home compatibility like Matter.
The Sifely Fingerprint Smart Deadbolt offers high-capacity user management with over 100 fingerprints and codes, suitable for busy households. It requires a separate gateway for full smart features, which is a notable trade-off for hub-free users. It is best suited for rental property managers and families needing flexible access logging.

Professional reviewers praise the eufy Smart Lock C33 for its seamless fingerprint integration, hassle-free installation, and family-friendly biometrics, deeming it ideal for rentals and garages. Editors highlight the reliable Wi-Fi app control and strong BHMA certification, but flag the Grade 3 rating as entry-level.
Everyday users appreciate the effortless family use, quick app setup, and reliable fingerprint performance for daily front door entry. The handle grip design and long battery life are frequently praised for reducing maintenance. However, recurring complaints focus on fingerprint recognition issues in wet conditions and faster-than-expected battery drain in high-traffic homes.
