Can't argue with it's results, especially on mold, absolutely no 'water' problems, and I have the hardest water available, just dry it off with the diapers. It helps to have a DEEP sink, or use it outside with the garden hose....I don't find it takes more than 4 minutes max per lp. Still use a VPI once it's cleaned with the Gemalog...and George's fluid is part of the secret for getting rid of the mold.
