+ Knife last forever. But after 3 days dull. + Knife not break, even when mower Stone caught. - Mowing was better with original Husquarna 1.8g. Husquarna mowers AC220. Lawn looks partially struppelig. + Fit screws and holes OK
Will initially using up the pack. If it takes too long not because 1 set holds 3 or more months. 1.8g original knife held last only 1 week.
