First of all. This is a solid shed and a good deal for the price. 

Second, I want to give a heartfelt apology to the person who said it took 6+ hours to assemble. I scoffed at the timeframe you stated and boy was I wrong. So very wrong. 

Warning #1: each piece is covered in a very thin film of plastic. I imagine this prevents scratches during shipping.  It tears easily so you have to remove it in tiny pieces. From ALL the parts. You will spend 2 hours on this alone. 

Warning #2: the metal is VERY SHARP. Either wear gloves or have a good supply of bandages handy. 

Warning #3: you will need at least two people to assemble. Or a third arm. 

Wayfair charges $300 to assemble this item. Which is approximately twice what I paid for it. At about screw #100 (out of 170), I was starting to think that it would have been worth it. 

It’s a nice shed. Good luck.
