After about 12 hours it is up. All I have to say cheep and poorly designed. I am a car mechanic, I take a transmission rebuilt any time over this job. As for the quality it's way too expansive for the quality. I do not recommend this product. You can not use power tool because some screws hard too hard to put in some are so easy to over torque so again because of the quality you must put all 400 +++ screws by had 
FYI I got the 15x8. After spending all this time putting it together I don't want to take it apart to return it. If it was easy job and I had the box, I would but I'm stuck with it.   
So you do what you like !
This is as real as it gets I don't know about other brand but I am very disappointed getting this shed.
