That darkened lower area on the sides of the tub where the porcelain is worn away is a good demonstration of just how hard these washers are on clothing you will never see that on any WP washer even a DD model.
I strongly disagree there. I have a large stack of vintage towels that have been washed in nothing but long stoke Maytags for almost 50 years (go back 3 generations). I have clothes from the early 90's that still get regularly worn and only show minimal wear from use, not from washing.
There is no way in hell my towels would live 50 years being washed in a DD shredder!!!!!!
