This shed took some time to put together but all the pieces were there and nothing was damaged.  We got it to store bicycles out of the elements, so we will see how long it will last.  It appears flimsy, however, I  researched on the internet the material this is made from and I read, "Polycarbonate is 250x stronger than regular window pane glass and 30x stronger than acrylic."  It looks nice and the skylight roof definitely lets in light.
