I have this unit since last spring, but in all honesty, that was probably nothing .... More than a mini graveyard hedge can therefore not edit. Everything else is wrangling and no cut, or it jams immediately., from clean Edging I have to continue dreaming. I do not know yes at what plant this device has been tested. Einhell I had more expected. Too bad, then the device is only still around .. There is only one star.
