Ridiculously difficult to set up and completely ineffective for smaller moles.  See YouTube videos as evidence of this.  It's pretty obvious that this is not a user friendly option for mole removal.  "Make sure you build up a mound of dirt, make sure that the jaws aren't encumbered by dirt or rocks, place leaves over the mechanism so it doesn't get stuck, etc."  Complete BS!  Steer clear of this.
