When this lock arrived and I felt the heft of the box I knew right away this was a quality product. There is just something about feeling the weight of the lock that lets you know it is heavy duty. The installation was fairly easy as most of the parts fit my current door without any modification. Once set up the lock app took a little while to update the lock firmware but after that it has been super easy to set up profiles and lock combinations. It's easy to get in and out of my home and is actually easier than if I were dealing with the key also provided. Enter the code and your good to go!
