This box is well built out of metal, rather easy and intuitive to use as well as set your combo on (i did not even read instructions).
i think this will suit most peoples needs for a lock box.
personally i bought it to hide a spare out here so i dont get locked out of the house again.
the combination dials are easy to turn and once you line it up with the proper combination you simply pull down on the front of it to hinge it open.
the shackle is robust and coated in rubber so it wont scratch your door handles. and it is also quite easy to remove so you can place it on different doors.
this unit also comes with mounting holes and hardware to affix it to a wall if that suits your fancy!
