Really nice feature

This is an awesome biometric feature. Just follow the manual and you have a fingerprint lock for your bedroom door. Or any interior door. Install is pretty standard and programming is a breeze. Just follow the included instructions.

Nice sturdy knob

This thing is big and feels nice and high quality. Not hard to program but the fingerprint sensor is a little touchy.

Great upgrade!

We recently had a run-in with a thief who managed to get inside the house and access one of our rooms, which luckily is just a storage room. With 5 household members going in and out of the room, it's fairly easy to forget to lock it and that is why I opted for this doorknob, since it locks automatically each time the door is closed. It is very easy to install and the app is good as well. The quality is there and the doorknob is solidly built. Haven't run into any issues as of yet.

Works perfectly

We installed the smart lock on our bedroom door. We wanted something that blended in with our other door hardware and didn't look like a lock. This door knob style lock works perfectly. It was easy to install, only taking a few minutes. All of the parts were included. Instructions were more than easy to follow. Just removing the original knob will give you all the instructions you need. The mobile app is user-friendly. It makes it as easy as possible to use and offers more advanced use as well. The fingerprint sensor has worked every time so we haven't had to use any other way to unlock it. It's great not having to use a key or keypad. The sensor is so discreet you wouldn't know it is there. Great for keeping snoopy kids out. The lock feels sturdy and reliable.
