The coverage is in order. For hard water, you need a larger quantity.
For washing results: I have bold colors combined with lighter and find that Spee holds the promise for color protection. But you should remain on the earth. It is very annoying when negative reviews are completed by other mid-Ster, because they have white washed with vigorous washing dyed and are now surprised that whites no longer is now pure white. With new laundry it goes without saying this to wash first with similar colors. So you should not expect miracles.
When cleaning performance and stain removal Spee "simply less Order" definitely is upgradeable. For example, my bright socks with earth and grass stains from gardening at low Temüeraturen are not really become clean. Even with the second washing phase, they were still stained.
I recommend Spee "simply less Order" therefore for colorful laundry (light and dark), which is easy to clean and has no stains.
