Product review (5 stars): Very quiet.  Worth the extra price
The drain pump on our 12 year old Duet washer finally gave out.  I passed on a slightly cheaper non-OEM part because a review noted how noisy it was.  I am so glad I did.  This one is whisper quiet.  I read concerns about how the discharge port had been moved but, due to the length and flexibility of the discharge line, I had no problem adapting.  Installation was straightforward (to simplify your job, attach the suction and discharge lines BEFORE you mount the pump to the washer base.  MUCH simpler to maneuver the spring clamps!).  You will get a lot of water out of the piping.  Drain it by slightly opening the suction strainer housing cover and sucking it up with a wet vac.  I also stuffed an old towel under the washer before starting.
