Reasons to buy

Dual-sided keyless security: Requires passcode authentication for both entry and exit, making it exceptionally safe for pool gates and child-proof enclosures.
Robust IPX6 weather resistance: Built with an all-weather zinc alloy shell that withstands heavy rain, snow, and extreme temperature fluctuations.
Anti-peep code protection: Allows typing random decoy numbers before or after your actual PIN to keep passcodes hidden from onlookers.
Generous user storage: Supports up to 50 custom passcodes per side for versatile family, guest, or employee access management.
Emergency power options: Features a Type-C USB backup interface to jump-start the keypad if the AAA batteries run completely flat.

Reasons to avoid

Requires double code entry: Typing a PIN to exit as well as enter may feel slightly inconvenient for low-security standard interior doors.
Lacks biometric fingerprint access: Authentication relies strictly on numeric PIN passcodes or physical backup keys.
No direct Wi-Fi app management: Operates primarily as an offline keypad lock, requiring manual programming directly on the keypads.
