Kwikset has been a leader in home doorknobs for quite some time. The installation is a little tricky. It's definitely not as fast as a regular doorknob. The set comes with basically everything you need other than tools. If your current knob is lined up according to the included templates, it's easier to install. If it's a new door and no holes already in place you'll need additional tools to install. The instructions are relatively easy to understand. I love the convenience of just using a code, but there are also keys. The finish is a modern brushed nickel. The lever type handles are smooth and easy to use. The unit runs on a 9v battery, which is also included.
