I just love Kwikset products. They are the brand I use exclusively in my home. I have never been disappointed in their performance. I tried to install the Arlington Handleset my self but was having a little difficultly figuring out the directions so I had to call on my handyman aka (husband) to help me. I love the lido lever. I've had this type of handle on my interior doors for awhile now. This set comes with smartkey security, which provides extra protection against breakin's by allowing you to re key your lock in seconds.
