Score: 88/100
Sifely Fingerprint Smart Deadbolt
Score: 75/100Rankings
The eufy Security Smart Lock C220 is a robust, hub-free Wi-Fi deadbolt featuring self-learning AI fingerprint recognition and BHMA Grade 3 durability. Its main drawback is the reliance on standard AA batteries without a rechargeable option. It is ideal for users in extreme weather environments or high-traffic households who prioritize reliability and ease of installation.
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.
