Product review (1 stars): broke after 2 1/2 years - buyer beware
The motor on my Duet Sport burned out after relatively light use and only two and a half years.  Of course that's long enough that the company won't cover the defective motor.  Plus, the unit has a design flaw which traps water and causes mold and mildew.  Whirlpool's customer service seemed neither surprised nor sympathetic when I called to arrange service and register a complaint.

Looking into Kenmore which I hear has a much better front load energy saving model.  I won't buy Whirlpool again.  Ever.
