Ultraloq Bolt
Score: 92/100Rankings
The ULTRALOQ Bolt Fingerprint WiFi Smart Deadbolt offers robust ANSI Grade 1 security with seamless native Apple Home integration. It features built-in WiFi and Thread support, eliminating the need for a separate hub for remote access. The main trade-off is the lack of a Micro-USB backup port and reliance on 2.4GHz WiFi.
The eufy Smart Lock C33 is a keyless deadbolt featuring integrated Wi-Fi and adaptive biometric fingerprint recognition. It offers easy installation and long battery life with AA batteries, making it ideal for rentals and garages. However, it has lower security ratings (Grade 3) and lacks advanced smart home compatibility like Matter.
