The product itself is pretty good.  Sturdy and good material even though my cat has no interest in it.  But the instructions are horrendous!  It's not difficult to put together but the instructions are so bad that it takes at least 1.5 to put together.  When you get to the last top portion of the condo, there is a part where you have to put your head inside the cat hole (if it fits) to screw in some pieces.  If your head is too big, too bad!  Take a shot in the dark and try to screw in things without seeing anything.
