Feedback - Door lock
The door lock on the left is an example of good feedback because when you lock the door the inside machanism makes a clicking sound that tells you the door is locked. While the one on the right has a bad feedback because when you turn the little knob at the center to lock the door, it does not look or sound like anything happened so you cannot be sure whether or not the door is locked.
