Product review (5 stars): Beats paying 250% markup through some service companies.
Replaced one that went out in my Samsung washing machine, and works like a champ (at least for the last 4 months) without any problems.  Beats the heck out of paying a technician to come replace it and mark up the pump by 250%, or buying a new machine all-together.  One note though, this unit did not fit my washing machine exactly, as I had to file down the insides of the existing housing unit/cover to make it fit over the pump.  Very minor issue in my estimation, and does not impact performance of the pump or the machine in general.
