When I first opened the box, I thought it was going to be more difficult to install, but installation was easy. It fit right into my existing deadbolt, and I followed the instructions included to put it all together. It looks great on my door with the doorknob. It matched well. The app setup was a little difficult. The app crashed two times and went off before I was finally able to commit setup. After get the it setup, it works seamlessly. I can lock and unlock my door from my phone or with the keypad. It was also easy to add my husband to the app so we can both use it. One thing I really like about the lock is the way I can set up a one time key code in case someone needs in my house. I also noticed in the app, it asks if it’s an air bnb code for people that own rentals. I think that’s awesome. It will also set up with your connected home automation things like Alexa. Overall, I am very impressed with the lock and would like to purchase another one for my other door.
