Well,  I got all the walls up really easy.  Everything was square and even.  Then I go to put on the roof panels.  Off by 8 inches. After 2 days of figuring it out.  We took all the metal bars out, put the entire thing together without those in.  Then when we got it put together, we put the metals in.  Had to create a few new holes.  DEFINITELY HAD TO PUT A BAG OF TOP SOIL ON TOP OF THE ROOF PANELS TO GET THEM ON! Would've have this a 4 star but the hours and hours it took to figure out the problem gives it 1 less star.
