The swiveling cutting head can be in inaccessible corners, and come to the tapering section. The battery can be loaded quickly and holds long enough so that it can "go around" creates. It is easy to use (the top of the handle) and expand - changing time about 10-15 seconds. The unit is well made, relatively easy and well tared / Balanced, so fatigue occur later! The Antippsystem for the automatic adjustment of the sink works well and the rotating nylon thread has no problems with grass, weeds and thin branches - in contrast to the trimmers with fixed plastic knives. One can the unit Recommend good and you do not necessarily have a spare battery in Petto (it takes about two hours patience for recharging - or it continues its work on nächstenTag - without intermediate stress - continues!
