I really thought I wanted the extra top row in my new dishwasher, but I think it is the thing I like the least about this model! Everything else I love! The look of the model is so sleek and it is a nice compliment in our kitchen. The performance is amazing. Our dishes are spotless and there is quite a bit of room for dishes. The top row/tier does not allow for tall glasses to fit in the second rack (thus my love-hate relationship with the third row), but it is great for laying out (flat) kitchen utensils for a good cleaning. Overall we are very satisfied with this purchase.
