(Las Vegas, NV)
While dishwashers have never been something at the top of my mind, I have to admit part of the reason behind that is the GE Nautilus - I've never had to really think about it. I've had friends and family have broken down dishwashers, but in my fours years of using the one that came with my condo this thing hasn't have any mechanical breakdowns.
It washes things well for the most part, though if you load it with some pots and pans, regardless of how crowded or not it gets in there, they'll come out with some white rings around it.
Maybe it's the the hard water we have here, but I haven't seen that at my friends' homes and water softeners haven't done the trick.
So apart from the useless "Pots" option this one's done very well for me overall with it's large space for dishes and efficient energy use. Overall, a B+!
