Score: 88/100Rankings

The Aqara Smart Lock U100 is a biometric deadbolt featuring a high-accuracy fingerprint sensor, multiple unlock methods, and extensive smart-home integration via Bluetooth, Zigbee and Apple Home Key. It is housed in a durable zinc-alloy body with IP65-rated outer panel, though the inner panel lacks weatherproofing. Ideal for families or shared households needing up to 50 biometric users and smart-home enthusiasts with Apple Home setups.

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.
