poor quality – I am assuming this model is the 'nautilus' . We had trouble with this machine very early on when The hinges fell off TWICE, the runners disintergrated and eventually the handle fell off . After only 5 years we were told all the plastic had gone brittle and the electronics needed replacing. Add this to the fact it was VERY hard to clean and often had to be turned off and on again to reset it when it started beeping and I would certainly not recommend it. However it did clean the dishes quiet well. poorly made, hard to clean did clean the dishes
