HEI LIANG Fingerprint Door Lock，Fingerprint and Keypad Input Smart Door knob, App Controlled Biometric Door Lock, Keyless Entry, Bedroom, Office, Hotel, Apartment Auto Door knob (Black)

Simple biometric interior fingerprint lock that works great.. The lock has a sturdy weight and metal / zinc casing. the price is inline with others. The lock offers additional protection and sanctity, which is important. I use it on my interior office door; thus, phone calls, privacy calls, stay indeed private. The app was easy to set up and offers many features. Moreover, I can UNLOCK the door for someone to enter from the app in about 1 second. No yelling, "WAIT, IM COMING!" Any DIY person that knows a flathead or slotted screw driver from a Philips will have the lock installed in 10-15 minutes. I truly get a kick out of using and hearing the lock secure itself. Good luck.

Interior door knob doesn’t securely insert and latch. Pulling on the doorknob removes the doorknob.

This fingerprint door lock is fantastic. It recognizes fingerprints instantly, opens super fast, and provides an amazing sense of security. I love not having to use keys and being able to register multiple fingerprints for the family. It works perfectly, and the battery lasts a very long time. Highly recommended!

I recently bought this door lock and I m impressed with this fingerprint and keypad smart doorknob. Installation was straightforward, and the build quality feels solid and reliable right out of the box. The sleek black finish gives it a modern look that fits perfectly with both home and office decor . it easily identifies registered prints and unlocks almost instantly. I really appreciate how convenient it is not to worry about carrying keys around, especially for rooms where I want a little extra privacy or security like a bedroom or home office.
