I thought I would like this door knob, since I already use Smartkey doors all over my house anyway, but when it arrived in the mail, I wasn’t as impressed with it. The depth of the knob itself is shallow and feels light weight and small. This knob would be more suited as a closet or bedroom door, but a key lock seems odd for either of those two settings. Lesson learned- go into the store to buy a door knob, rather than online.
