Score: 78/100Rankings
The eufy Security Smart Lock C220 is a hub-free, Wi-Fi-enabled deadbolt featuring self-learning AI fingerprint recognition and BHMA Grade 3 durability. It offers six unlock methods and up to 8 months of battery life, making it suitable for high-traffic households. The main trade-off is the reliance on 8 AA batteries without a rechargeable option, which may require frequent maintenance.
The samtechT Bluetooth Fingerprint Smart Lock offers a robust ANSI Grade 2 motorized deadbolt with UL fire-resistance and versatile entry options. Its main drawback is the bulkier handle design and occasional app connectivity issues. It is best suited for homeowners seeking a budget-friendly DIY upgrade with guest code management.
