Beautiful door.  The color is rich and looks old world.  You do have to assemble the door, but you shouldn't be surprised because assembly instructions are in the Specification details.   Only issue....Studs are normally 16" apart.  The bracket pre-drilled holes are 17 1/2-18" apart and if you're installing over an interior door, there is no header; therefore I had to buy a 1x3 board, stain it, attach it to the studs, and attach the door bracket to the header I installed.  A little extra work.
