The Quality
I use the fabric softener so mostly only for our already mentioned towels, these are the softener application really nice soft and fluffy. The scent I can (to date about 6 weeks) significantly perceive still even a few weeks, when I open our linen closet.
My Conclusion
I do not use the product at temperatures just very happy and I think that I will but otherwise take my Lenorsorten again in the summer. Softener stains or residues I could not watch even though I washed many white towels and bath towels with it.
