Instead of 2 left and 2 right corners they sent 3 right and 1 left.  They did send me the missing part in a couple of days.  Parts did not fit together as easily as I thought they should.  The included shelf did not seem to fit like it should. I went into it today and one end was detached and sagging, due the building shifting some. The shed does look nice.  I hope it holds up. I was able to assemble it without assistance with the use of a lot of clamps and bands.
