We chose this model over competitors because it fit the space the best. It turns out, it washes very well and is much, much quieter than the old unit it replaced. Also, the space inside is designed well. You can fit larger items far more easily than you could with the older unit. The salesman showed me that there are three washing "choppers," the two usual on each level, plus an extra one on the top. Quick Wash cycle gets the dishes done fast and clean, comparable to Normal or Heavy cycle. Unlike competitors, this dishwasher has a heating element included--and that was also a big factor in the decision.
