Professional reviewers position the Sifely keyless fingerprint lock as a budget-friendly, easy-install option with strong suitability for indoor, family, and light exterior use. They caution against relying on it in consistently harsh outdoor conditions or for users with very high-moisture or dirt-prone environments, noting that fingerprint reliability under wet conditions is less stable than higher-end competitors.
Everyday users tend to rate this lock highly for interior use and protected entry doors, praising its ease of installation and value for money. The main caveats reported by consumers are conditional grip on fingerprint recognition when hands are wet or dirty, and the need for a gateway to enable full remote features.
Professional reviewers commend the U100 for its precise fingerprint sensor, Apple HomeKey compatibility, solid auto-lock functionality, and impressive eight-month battery life. They also note the lock's robust zinc construction, IP65-rated outer panel, and reliable Zigbee performance when used with an Aqara hub, while calling out the need for a hub for full feature access and the non-weather-proof inner panel.
Everyday users generally praise the lock's versatility, long battery life, and weather-resistant outer housing, especially valuing the multiple unlock options and local data security. Recurring complaints focus on the requirement of an extra hub for advanced smart-home features, the inner panel's lack of weatherproofing, and the relatively heavy weight during installation.
