We've been looking for a new door knob for on our front door and we really didn't want one of those ones that felt kind of loose when you turned it or hollow sounding, so I was happy when I got a chance to try this one out. The picture online makes it look like just an ordinary knob but that doesn't do it justice. I was surprised at how heavy it was when I took it out of the box. The knob felt so sturdy  and heavy duty and when I put it on (which it looked great) it didn't feel loose at all and the keys (which look and feel pretty durable too) fit and turned easily. I love the smart keyboard feature now if I lose my keys I won't have to buy another knob, just use the special smartkey to set a new lock and get new keys made that's awesome. I also git the matching deadbolt so now my house feels safer than it ever has.
