I purchased this shed 3 weeks ago and finally finished putting it together. Did most of the work myself. Only needed help occasionally to hold walls in place until corner supports were in place. Having a level base is key so that all parts line up to be screwed together. Pay attention to all the instructions including special notes, so that way things will fit together properly and work as intended when you are done.  Love the skylights which allow ample light in and the fact that the windows open is a great feature for ventilation since I store all my lawn equipment in there. Love the 2nd door on the right side to keep the lawn tractor out of the way. Anyone looking for a great storage shed that comes with a ton of great features inside and out, don't hesitate to make Lifetime Products your next investment. Love this product!!!
