    Functional but this is not satin nickel. Actual piece...
    Functional but this is not satin nickel. Actual piece is chrome; not as pictured. Package says satin nickel, so this is mis-named at the manufacturer level.

    Won't work with molding
    Because my doors have moldings around them, this lock doesn't work. The distance between the stationary piece and the swinging arm is too small, so they won't line up properly to function. Without moldings, it looks like a great,strong security lock. But, since nowadays most doors have moldings, this item is pretty worthless.

      Good swing door guard for doors flush with the jamb
      My door is offset by 3/4" from the edge of the door jamb. The stationary piece does not extend high enough to clear the offset and fit into the moveable piece. It looks like a good product for doors without an offset, however.
