Functions exactly as expected, looks sleek, has lots of features. The companion app provides lots of custom configuration. The fingerprint scanner itself works well, and grants quick easy access. The power efficiency seems great, as my first set of batteries have lasted almost a year now. Even if batteries fail on you, the backup charging port and physical key ensure you’re never truly locked out. I almost want one on every door of the house just for baby proofing.

I recently installed the Fingerprint Smart Door Knob with Biometric Door Lock, and it’s been a great addition to my home so far.Pros:✅ Fast & Reliable Access: The fingerprint recognition works quickly and accurately, providing keyless entry with ease. It’s super convenient, especially when my hands are full.✅ Modern Design: The sleek, stylish look adds a modern touch to the door, blending well with any décor.✅ Easy Installation: Installation was straightforward, fitting standard door sizes perfectly without the need for professional help.✅ Solid Battery Life: So far, the battery life has been impressive, and it’s held up well without any performance issues.Cons:⚠️ Long-Term Durability Unknown: While it’s been great so far, I’m curious to see how well it holds up over time, especially with frequent use.⚠️ No Backup Key (Optional Concern): Some models don’t include a physical key option, which could be a concern if the battery dies unexpectedly—but so far, no issues here.Final Thoughts:The Fingerprint Smart Door Knob has been a reliable, convenient, and modern solution for keyless entry. It’s worked flawlessly so far, and I’m really happy with the purchase. Definitely recommend it if you’re looking for a smart, secure upgrade!

The door lock was easy to install and program. I love the biometric feature, so much easier than trying to find the numbers on a key pad in the dark. The dark finish goes well with our current hardware. Great product, would highly recommend.

This door lock is amazing. So easy to set up. There’s also several cool settings included that are super useful. You can set different fingerprints for different people, you can use the keypad to set different key codes as well. There’s even a feature where you can have notifications sent to your phone whenever someone tries to open the door, enters in the wrong code or pint etc. for a small fee, the lock can even be automated to call the police. The lock is also solid, heavy and sturdy and a good size. The app is easy to use. Would recommend and will definitely buy again for other doors.
