Worth the money!

I have 3 kids still at home. Every time I turned around one of them had misplaced our house key. I mean it never failed. I wanted to run out and purchase stock in the key manufacturer I was needing to replace them so often. Then one day I came home to find that someone had been in our house and had stolen from us. This purchase has given me peace of mind. You can customize it in so many different ways to fit each child's different needs. Whether it be a key, a code or a fingerprint. You can even look on the app and see which person unlock the door and how they unlocked it and at what time. If I had to say anything bad about it, it would only be that if you unlock it with the key, it does not show up.

Great smart lock if you do not need a deadbolt. fingerprint sensor can be glitchy but that has happened with 2 other brands and my thumbprint. Other's print seems to work more efficiently. Don't hesitate, buy and try as they are usually sold out.

This item worked well. Had to buy a 5 inch latch. The square spindle was larger then the standard, I had to modify the 5 inch latch to make it work on the spindle.
