The unit comes disassembled, but is easily assembled by following the instructions. I recommend you take the time to properly adjust the harness attachment and the handle to balance the unit to suit your height, this will ensure a good working position and less tiring to use. Once all mounted correctly, it does not move.
I never used the blade, but only twice over. I had to readjust from the coil winding delivered so that both strands out correctly. The electric motor of 1200W is very powerful, and this unit is not a single border cut but actually slightly trimmer can efficiently clean a cluttered garden. If you are looking for a simple cut to perfect edge finishes of your lawn, it is not necessarily the equipment you need. It will be very useful for against for heavier work.
The use is secured by a dual limiting accidental rotation of the son. The handles are comfortable and the unit is relatively light, although as any device worn on the shoulder, it will cause some fatigue in the long run.
In summary, this is a good, lightweight and powerful, offered at less than 100 euros. I recommend it.
