Shed is vinyl, I assumed that will be different quality. It's like your siding on your house. Manual needs to be redone. I think some steps are missing or not listed well. You need to have two people to do it (took us 2 days without ground preparation and picking up plywood). I don't recommend to put it on the ground without stepping stone or concrete.  Don't do it if it's windy, pieces will fly all over. I like the shed, it's nice looking, almost matching with my house siding. It is good size. Overall I will buy it again, but please redo the instruction.
