Product review (5 stars): Actually better than the bins that came with my fridge originally
5 months after buying this replacement shelf from Amazon seller Free Shipping LLC, it is still going strong.  I wouldn't know how to verify OEM parts (it's important to check the feedback ratings of 3rd party vendors!!!), but it certainly fit as though it was made for my 12 year old, Costco purchased Kirkland by Whirlpool fridge (model # GDSSHAXLB02), whose own original drawers were thin, unreinforced, brittle, and looked very different from this one.  I spoke to Whirlpool parts in the past and they don't stock the orginal part because they know there's a breakage issue, but drawers like this, standard on slightly higher end models from the same year, work just as well.  Better, actually.

If it happens that you have my model or any refrigerator that takes the W10321304 bin, you should be fine, but one tip:  you'll have to give it a bit of a thump to initially seat it into the grooves it fits over.  (I did have a moment of panic thinking that it was too tight or the wrong drawer.)
