I have been using Cheer for many years and I love it. I have 6 children and it is the only detergent that I have found that will get clothes clean and also be gentle on their skin (I have had problems with Tide and Kirkland brands making a few of my children and my husband break out).
There have been a few times when, in the quest to save money on laundry detergent, I have tried out other brands.
I have always went back to Cheer. For tough stains, it also works great as a pre-spot.
