Editor's Pick: When your hands are full with groceries or packages, just place your palm on the lock and it opens — no need to free up a finger to press a fingerprint sensor. Palm vein recognition relies on the blood vessel patterns beneath the skin, so peeling fingers, sweat, or water won't affect it, and you don't need to take off your gloves in winter. The 7800mAh battery lasts over half a year on a single charge, and low battery alerts appear in the app ahead of time, so you won't suddenly get locked out. It supports WiFi remote access and voice assistants, so you can let visitors in remotely even when you're away.
