I've been looking into updating the doorknobs and deadbolts on the house and this was perfect.  It makes entry so easy.  The installation was very straightforward and I had no issues doing it myself.  It's a sleek design, easy to program and I love the security features.  The screen can be difficult to light up at times but usually works if you swipe your hand a couple of times. Our door has a weather seal and we have to pull the know to get the deadbolt to lock properly, but without the weather seal it would be perfect.  The look and functionality are just what I was hoping for. A quality product!
