Product review (3 stars): Fixes slam door damage
I'm guessing most people buy this for the same reason.  Somebody lets a violent temper out, slams the refrigerator door very hard, and the items in the door just keep going, breaking the shelf.  This is an exact replacement part if it fits your fridge, though you will want to hot glue it in if the door liner was damaged -- do your homework to make sure it is for your model though.  Snap a photo of the model number on the boilerplate inside the fridge, then pull up the parts diagrams on the GE Appliances website for your model.  Model numbers are listed exactly, then you can buy the part much cheaper on Amazon.  I'm still docking a couple stars because the price is still outrageous for what little this must cost to make.  But it is still cheaper than buying a new fridge...
