Shed once built is worth the money. Says 2 to 3 hours and takes 2 people. That won’t happen. Issue is with the instructions which are pictures only. Many pieces can go together more than one way and if put in backwards you will not realize it until many steps down the road. You then have to go back and undo pieces.  If I was building a second shed just like this then I think 2 to 3 hours could be realistic. 
Give yourself plenty of time to put it together and I think you will be satisfied. I know I am now that it’s together.
