Product review (5 stars): The plastic replacement will only break again.  Purchase the metal part. Totally pleased.
Purchased this metal product to replace the existing plastic product that broke within three years of original purchase.  The plastic replacement will only break again.  Purchase the metal part.  I have had these for only three months (Yes, I agree not enough time for a valid quality review, but if you are at all handy, you can tell this part will last much longer). Totally pleased.  Search YouTube for directions on installing.
