One of the worst products I've seen short of what comes from that far Eastern crazy cheap online where the freight costs more than the product.  --  These bins are so flimsy the sides bowed in.  They couldn't be stacked empty let alone have anything in them.  I barely tripped over one and it severly cracked and broke beyond use.  I regret not sending it back for a refund in a timely manner.  No more Iris products for me!
