I have one of these on most of the doors in my house. I love that you can program it to automatically lock after a given time period. No more worrying whether I left a door unlocked. And no more worrying about getting into the house if I lose my keys! And they're relatively easy to install.
Neither of the units I bought worked with any of the phones we tried for setup. The app (which is the only way to set them up) did not function properly on Android or iOS. Even returning them has been difficult, so I cannot recommend trying this lock.
I bought this lock for our front door a few years ago, and it is still going strong. Batteries last me about 1 year, and the buttons are very nice to press. I get notifications when the door is locked or unlocked, and it's nice to be able to let family members in when on vacation to feed the cats. I would recommend this to lock to anyone looking to add some smart capability to their home! the only gripe I have about it is that sometimes the tamper alarm goes off for no reason and I need to remove the batteries to restart it. This has happened probably 3 times since 2019
