Product review (5 stars): I've ordered three of these and would do so again.
Fast shipping and good customer service from Deep Discounts.  Some reviewers remarked that these are cheap foreign parts that wear out prematurely.  I have not found that to be the case.  I have ordered three for the same machine because I had an undiagnosed systemic problem causing them to wear out in the span of about 1-2 years.  The pad on the tub brake was gumming up, grabbing too hard and stopping the tub too quickly, resulting in excessive torque on the sacrificial coupler.  One reviewer said coupler lasted only a few cycles.  If the spin cycle stops within a second or two of opening the lid, it's putting out too much torque.  One sign of this I noticed is catastrophic failure, that is, instead of one or two of the six legs bent or broken, all six are snapped or the rubber is torn. With the brake fixed, there have been no problems.  My experience is that it is not the coupler that is at fault; it is some other part of the system.  This coupler functions as it is supposed to: to fail first and so protect the more expensive components of the system from failure.
