Review: Adel 3398 Biometric Fingerprint Keyless Door Lock

adel-3398Summary: The Adel 3398 biometric fingerprint keyless door lock is well built and recognizes fingerprints fast, but is not very accurate. I recommend the Samsung SHS-P718 LBK/LMK lock instead. It’s more reliable and it comes with many extra security features.
