My daughter loves bubbles. So I once brought her from shopping a little bottle of no-name. What a disappointment. It emerged barely bubbles, the stuff dripped and at all we have done us very hard. In another bottle, a similar picture. My daughter was quite disillusioned when my husband came with Pustefix ... and lo and behold wonderful bubbles easily. Why? I do not know either. I have nothing against No Name products or homemade bubble liquid. Maybe I can just or had not no luck. I can say that I have never had bad luck with Pustefix! Even my daughter (almost 3 years) can thus blow wonderful bubbles. It's still fun for the whole family. And in this value pack, which lasts a long time, even quite favorable. Whether for us, for birthdays or other events, I have only Pustefix - in large supply for the summer :-)
