I was a product tester for this item.  I used this along with my GrabGreen detergent and it seemed to work just fine.  The packets dissolved like magic in cold water and there was no residue left on any clothing.

I didn't see any AMAZING change in my clothing but I didn't see any negative effects either.  I don't use a bleach alternative on a normal basis so I didn't have any real comparison as to how well it works against another brand.

All my clothes came out clean and smelled great.
