Score: 88/100
Yale August Silver
Score: 85/100Rankings

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 Yale August Wi-Fi Smart Lock is a premium retrofit solution that offers built-in Wi-Fi and fingerprint biometrics for keyless entry. Its main trade-off is the high cost associated with purchasing the Keypad Touch separately and limited compatibility with single-cylinder deadbolts. It is best suited for renters or homeowners seeking a non-intrusive upgrade with advanced smart home integration.
