So I must say I am always impressed by the Persil powder detergents. I have previously washed exclusively with liquid detergent, until I read that they were "underground" evaluated Warentest. Am now switched to Persil powder and have to say that the results visible (!) Are better. No more gray haze. Great Colors. All spots (with whom I had previously problems) are out. And it also does smell wonderful! The price in the "XXL" of course, is unbeatable. Therefore deserved 5 stars! Strong buy recommendation!
