It was mostly easy to put together.  The last page instructed small screws be used to hold on the back panel.  Only there weren't any pre-drilled holes for the screws.  For now, I'm using velcro to hold it on but will likely switch to thumb tacks hammered in.  It's also a bit wobbly if you have to move it.  I tightened all of the screws, and it's still a bit wobbly.
