Extremely cheep product.   The top two shelves sit on top of the three bottom shelves with only tiny wood dowels and a cam and attachment on both sides.  Once put together, they do not stay together.  The "screw" thing just pops out and the top two shelves just come right off.  Shipping was $25.00, so total price was about $100.00, way to much for this unsafe cheap shelf.  Have to somehow reinforce it so it won't just fall apart.
