I'll start out with this, do not try and assemble on a real windy day!  Also, have everything sorted out and plan to have two people to assemble the shed.  A handy person can probably do it in one day, ours took two but it's a very nice shed with lots of room.  We've had two heavy rains and there are no leaks.  We put ours on a cement pad.  It's really nice that you can put the two windows on any of the walls.  It so happened that one long wall was up against our block wall and the other faced our house where there would be very little sun so we put both windows on the wall opposite the doors and it worked out great.  My hubby wanted the film left on the windows so no one could see in and there is plenty of light.  Overall it seems worth the money!
