I assembled this shed in a day by my self, instructions were OK but the videos in the app were perfect. I do recommend using sawhorses to assist in assembly, particularly to save your back. 
I had one faulty part but Charlotte from customer service immediately solved the problem in one short call and had a new part shipped out very quickly. Awesome customer service!
I replaced some screws with colour matched pop rivets to increase security as my shed is at the front of my property.
