The description of the shed includes shelves however, this does not come with shelves which is why I took away one of the stars. It does seem pretty flimsy but once put together, it holds together well. I did make a base with 2x4 and secured the metal Fran to it. Then I used concrete stakes to hold it into the ground because the winds where I live are really strong. I plan to reinforce the inside with wood to make it more structurally sound  and although the roof is screwed on secure, I want to figure out a way to reinforce it from the wind. I’m using this as a chicken coop which is why I chose this 5x4 so this one does give a bit more room. Overall the shed is ok but do plan to add a bit of money to make it more solid.
