What Experts Agree On
What Experts Love
- โ Palm-vein recognition with a lightning-fast 0.3 seconds response time hits 99.99% accuracy and, reviewers note, works great in the dark, so it reads your hand the instant you reach the door.
- โ A 7800mAh rechargeable battery charges over USB-C and lasts roughly 6 months per charge, with an emergency power port so a dead pack never locks you out.
- โ Five unlock methods (palm vein, up to 50 PINs, key fob, the app, and a physical key) cover every fallback, and at $129.99 it is the cheapest hands-free biometric lock in this lineup.
- โ An IP54 weatherproof rating handles rain and dust at the front door, and palm-vein reading is unaffected by dry, aged, or wet hands that defeat fingerprint locks.
Common Criticisms
- โ It unlocks by palm vein, not face, and you must hold your hand at a consistent distance, which takes more adjustment than a fingerprint pad.
- โ It runs on the generic Tuya Smart Life app reviewers call clunky, with no Apple HomeKit or Matter support and no built-in door-open sensor.
