I LURVE my dishwasher. Its a LG and it works really well- I've never had to clean it out (maybe I am dodgey about this!), and it doesn't make my glasses cloudy. I would run it 2-3 times a week and just use those little 'pellet' things you can buy- super easy.

As far as smell, they can smell. But you can get these little lemon things that you hook in the dishwasher and they make it smell all yummy.

Oh, I also like my LG because it has child-lock. Important when there are all those pretty lights!!
