I installed this about two months ago. Our family of five is coming and going quite a bit. We also have family and guests who stop in. It's great not to have to hide a key and then worry if someone remembers to put it back. The view to the outside is stylish; the view on the inside looks a little bulky and detracts a little from the look of the door. That's the only reason I scored it 4 stars. The convenience more than makes up for this.
