I use these softener already be a long time, because I can not stand the rather aggressive smelling perfumes of other fabric softener, can I get on a bad headache. However, I buy the Ecover softener Sensitive with purenature.de, where he is offered the bottle for 2.99. In the above vendors through Amazon, the price is too high to me. The softener is highly recommended not only for people with allergies, for the sake of the environment.
