Product review (2 stars): Cheap Replacement, But Doesn't Last
I bought and installed this on my Whirlpool Duet (Model #: GHW9100LQ) in February 2016. It broke and stopped working in June 2017. Yes, it's an inexpensive replacement part, but, as others have mentioned, it doesn't last. I went ahead and went to my local appliance parts store and purchased the full Washer Drain Pump Assembly, which was about $130. The full assembly looks more like the OEM part so hopefully it will last longer.

I've added a photo of the pump showing the broken plastic impeller.
