If I was just rating the shelves I would give them five stars.  They are sturdy and easy to put together.  However, the company that these shelves come from put absolutely no package protection inside of the box.  They simply drop the shelves in the box, tape it closed and send it to be shipped.  I ordered three of these shelves, which were shipped in three separate boxes, and two of the three shelves had breakage.  Since I didn’t want to go to the trouble of returning them (something that works in their favor), I got out duck tape and gorilla glue and did the repairs myself.  These shelves were used for storage in my garage.
