Now, as a conclusion we can only say, it does not act. Not even when the clip remained in place, the trees in the Prater was able to recover. According to my husband, it should not even have rudimentary given an improvement.
Also from the "more air" unfortunately I have not even rudimentarily realized something. That's a real shame because I would have been there really expected me about.
I can not say anything positive so unfortunately, so there is of me only one star.
