Score: 88/100Rankings
The ULTRALOQ U-Bolt is a versatile smart deadbolt offering high security with ANSI Grade 1 certification and Matter-over-Thread compatibility. It features a large fingerprint capacity and IP65 weatherproofing, making it durable for outdoor use. However, remote access capabilities are limited without purchasing an additional bridge.
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.
