agitators
I've had the DA in it for a few years. I switched them because as well as the Surgilator works, it's a little rough. It also tends to add loads of air into sheets and other flat linens. I like the DA because it can wash a huge amount of clothes and I find it much more gentle than other agitators. I am always washing very delicate sweaters so I want the least "vigorous" agitator in my machine. Overall, the DA is my favorite performer.
