" These washer drums (4.5 cu.ft. to 5.0 cu.ft or larger) do not compare to a 7.8 to 8.0 cu.ft. (or larger) dedicated dryer. "

Right, but they're not intended for people who have the space and money for a dedicated large capacity dryer. They're another tool in the laundry toolbox.

I think they're a great idea, and will help a lot of people who have homes with little space, or water hookups in places that offer few options that don't involve big bucks in reconstruction.
