Harfo Fingerprint Lock
Score: 72/100
eufy Smart Lock C33
Score: 78/100Rankings
The eufy Smart Lock C33 is a keyless deadbolt featuring integrated Wi-Fi and adaptive biometric fingerprint recognition for easy, hub-free remote access. It offers multiple unlock methods and a hassle-free installation process, making it ideal for renters and families. However, it lacks the highest security grade and native Apple Home compatibility found in some competitors.
The Harfo Fingerprint Door Lock offers robust keyless entry with high-accuracy fingerprint scanning and multiple access methods. Its main limitation is the poor visibility of the touchscreen keypad in daylight and the need for a separate gateway for smart features. It is best suited for users prioritizing keyless convenience and durability over advanced smart home integration.
