Review on 🔒 Smart Fingerprint Door Lock - Biometric Keyless Entry Door Knob for Homes, Apartments, Office, AirBnB, Hotels (Silver) by Travis Petty

That was the easiest installation ever. This corresponds to replacing a normal door handle plus an inner plug. The instructions are short and programming is also a breeze. I never had a problem getting into the room. My husband sometimes has to wipe his thumb - it's either dirty or wet. Then he enters. However, I would not go back to my old door knob. This is another added layer of security for household firearms, although this lock is securely fastened it adds an extra level of child protection. Highly recommended! At this price and quality you would be foolish not to have it.
