Product review (4 stars): Not well designed, but not the fault of the seller or this replacement part
The part I got was as good as original. As other reviewers not, it's not designed particularly well. I believe when the vegetable drawers are extended all the way out, the weight of the drawer fatigues the plastic at the end of the guide, eventually causing it to fail. Still there's nothing wrong with this replacement part. It works great; but for how long? I recommend putting some mineral oil and/or soap on the drawer slides and the track on this part. Greatly improved the operation of the drawers, even when very full. YMMV.
