RainBarrel
Worked quite well as a rinse added softener, but was not so fabulous as a wash added softener.
It did have a nice scent.
When it was out, I was doing most of the laundry for Ma, my sister, and me, and I was allowed to choose the chemicals by then, too. I alternated RainBarrel with Downy.
I found its bottle to be particularly easy to handle.
