It works great!
It took 15 minutes to install. I downloaded the app and programmed my password, I added my fingerprint and bang, it’s done. It’s easy to add additional fingerprints. The Fob works great. I have the key as a back up. I am able to text an e-key if needed to family when needed. I’m thinking about adding an additional lock to my home office to secure that area when having gatherings in our home. Great looking, definitely recommend!

Good item, must use app
Why did you pick this product vs others?:Good product, easy to install. My only downfall is you have to use the app.

Excellent choice
This lock is for my bedroom. It’s really the holy grail of door locks; auto lock, biometric, keys, fob, and code.I was a little disappointed when I realized that it was not able to connect to my Alexa as advertised, but overall I love it. It was easy to install, setup and use. Excellent choice.

A must buy. Stop looking.
This is a great lock, it's my 2nd one. The finger print reader is a selling point, touch the door reader and unlocked. No more caring keys!!

Fast install and user friendly app
App is very user friendly and they provide different length screws for different door depths. Very well made product and an affordable price. I didn't want to submit a review until I had used the product for a while. I've actually bought two more since the first one.

After a year it dies...
So this would be my 2nd time buying this type of knob. I had one prior that stopped working after a year of being used. This knob has now officially stopped working as well. I purchased it on Nov. 2023, it's now April 2025, so 1 year 5 months. It suddenly stopped working, the sound comes on says "unlocked" but the knob no matter what way you rotate it, doesn't unlatch. I don't know what it is about these knobs that they just suddenly give up out of the blue. Throughout the time I had it and it worked, it connected easily to my phone. It was easy to install and program, overall a straight fwd product. I would rate it higher but it has more downfalls then up. For starters, it can be a hassle to register your thumb if you use that feature. If 5 times I tried it, maybe 2 times it unlocked at the 1st try. If you use the numbers, it can be easier but when it wants to act up it will. So it will start to not register the correct number and from my experience, I would have to reset the whole thing again, make a new code & then it would work for a few weeks. Like any electronic device, if it catches some rain it won't work properly but that can be overlooked since even phones do that. Would i recommend this product... probably not. Simply because if they all work this way, you'll need to replace them after about a year to a year and a half. Do you really want to be spending $60 to $100+ every year on a knob? I don't... so i guess I'll be going back to the old fashion stuff and hope better technology gets developed and later maybe try again...
