I bought the product, in the hope that the weed for a while denied me, Unfortunately that was not the case. In the first application on the terrace, it has so far as just fine, so after 1-2 days the weeds was broken, well so far, but now the problem, none 2 weeks later reappeared weeds and to make points even worse. But anscheinet that works better for others, why I do not know, although I was very generous with the application, in the end I did it tipped even Pur plan, wait times like this manifested now.
PS. The stuff has an unpleasant odor, even if it is mixed with water, were also one or two complaints about the smell, which also lasted so for 3 days.
Well, had better weed killer who has first not so smelly and its effect has lasted much longer, although this has not worked so quickly with the destruction, but longer weed free.
