Horrible…assembly was a nightmare.  The plastic was impossible to remove, edges were so sharp…just about cut off my toe as one sheet was stuck to another and slid down onto my foot as I moved it.  The holes for the roof did not match up, but at that point 2 days were invested in the assembly so we were not about to take it down and return it.  The sheds are on a solid cement pad, After less than 6 months they have both settled to the point that the doors no longer align with the holes in the base so there is a gap.  Apparently there is only a 30 day warranty.  Worst customer service ever, I have never had this issue with Wayfair with prior purchases, sad to say that I do not think I will ever shop Wayfair again.
