"A feature-rich smart lock whose convenience is directly tied to its battery consumption."
The 'Built-in WiFi' means this lock connects directly to your router without a separate plug-in hub, simplifying setup. The consequence is that the lock's own disposable batteries must power a power-hungry WiFi radio for any remote commands.
This lock is for the tech-savvy user or rental host maximizing features-per-dollar, prioritizing fingerprint access and direct remote control. If you want a complete feature set at a competitive price and don't mind managing battery changes, the value proposition is strong.
Anyone prioritizing maximum longevity and 'set-it-and-forget-it' reliability should be cautious. The physics of powering WiFi with AA batteries and the notable rate of negative reviews point to a higher maintenance burden than some competing systems.
