Very mediocre to bad head. The only positive thing is the very easy and stable placement of the trimmer line. Unfortunately, everything else is a disadvantage. Very poor balance that is evident at first glance, resulting in even more trembling of the trimmer. The second disadvantage is that the whole concept of easy trimmer line placement makes it very wide, resulting in cutting space from the trimmer line and cutting range. Finally, there is no possibility of placing 4-wire cables in a cross. Clever design as an idea but with significant shortcomings.
