I like the needles very happy when "Festhäkler" I prefer that, the slide well. AAAAB: The needle gauge is not always true. In the set I have 4 needles, whose strength does not correspond to the declared. The 8 corresponds to 100% of the 7 Series, the other deviations are 3.5 instead of 4, 3.25 instead of 3.5 and 3.5 instead of 3.75.
