Never have tried it before.
I was really hoping this product would "lighten my load" and was frusterated to find that after a couple cycles it came out of it's holder which required contantly putting it back in for the next load, kind of a sticky experience. The smell didn't stay strong for long, and the bar eventually broke. The traditional sheets are just easier.
It fell off the first time I used it and left a residue on my clothes.
Just plain doesn't work for me. It leaves a waxy residue that I don't get with Downy, and then the sticky mess from the bar is impossible to remove! And since I occassionally need to dry things without "fabric softener," it was a real pain to have to hang them. I was so hopeful, but it was a definite thumbs down for me.
