Have a plot on which everything is allowed to grow. Every now and then I have to intervene ...... grasses and various wild herbs grow over my head. This cordless trimmer helps. A 220V line trimmer failed and me is the coil flown around the ears - pulled from the motor shaft. Since I already have the battery system by Bosch and batteries and charger are available was obvious the acquisition. After tentative attempts I ventured on a path through blueberries - stem the device easily. That's hard wood and no grass! For the pruning of panel joints I ordered as a spare part the string dispenser for a Bosch 220 volt unit. (If in other contributions described). Battery life is OK, the included 1.5Ah battery becomes flat relatively quickly. But I have two batteries from 2Ah screwdriver. Place still images one - so I'm excited.
