I received my handle and set it up as prompted to. I installed it on the door and tried charging the battery (which did not go up at all), and after installation, when I tried to use the handle it would not wake up to type in the code, nor would it allow me to use the fingerprint function. It’s almost like it’s dead all the time and the only way to use it is by having it plugged in.

The door knob has several fancy features. But none of them would make any sense, if it didn’t work as a secure doorknob. It actually does that very well.The other feature that I really like is being able to use my thumbprint to unlock and open the door.
If you have ever installed a doorknob or replaced one, there will be no surprises. When you install this one, the one unusual step is hooking up the small ribbon cable that goes through the door. It’s simple and straightforward.
I’m still carrying the key with me for a while until I trust it to work reliably keyless, which it has so far.
I’m 100% happy with this upgrade that I made to my front door, and I will recommend it to friends and family too! (That’s probably my highest praise for a product like this.)

I’ve had this for maybe a year and a half and had I not had my phone to manually unlock the door from the app outside of the room the door this handle was on, it would have been an inconvenient and costly fix due to finger print and code completely not working, not to mention the charge on the battery is junk. Although I thought this was a great solution this model has too many malfunctions and I can’t take that kind of risk.

I put this on my basement door and it is the best thing I could have done!

This is looks great, very easy to install and program with TUYA App using Bluetooth connection. You can use the App to register the fingerprints, codes and also to open unlock it.
Use 2 battery AA, came with 2 keys in case the batteries dies, and also you can connect a external battery using USB to opened in case the battery dies.
The fingerprint scan works, but in my case I have to register the same finger twice to make work better.
The keypad stop works after a week, don’t know why… But then start working again few days later.
Overall, it’s a great lock, so far so good, and for the price, it’s a great choice!
