When I first got this item one of the clips that holds the bottom shelf was broken.  I left the shelf on it with the remaining 3 clips holding the shelf while I was going to look at Lowes for a better solution.  Nothing was on the shelf at all.  Tonight the bottom shelf just fell down after the remaining shelf clips just broke in half.  This shelf weighs all of 5 or so pounds if that.  Absolutely pathetic quality hardware.
