Weeks of fragrance ??? Not at all, shortly after the opening of the washing machine suggests a slight "Düftchen" counter, but that's about it for now. After drying, you have to the linens almost "aufriechen" to hint to which scent was used ..... let alone when treating towels in the dryer because you can smell unlike z. Ex. Lenor silane or even nothing more.
Two stars, because after all, the laundry is soft, but the lack of smell (especially if it is being touted as great) - a no-go. Will no longer be ordered, rather spend a little more money and rely on established products.
