It's my first time using wool balls with an essential oil, I had always used dryer sheets. I won't be returning to dryer sheets. At first, I thought the Sun Is Shining oil was a bit too strong, but after using it on a few loads of laundry, I'm really happy with it. My laundry smells amazing. It's not an overpowering scent and I'm already planning on buying more of this oil. Happy that I've kicked dryer sheets to the curb.
