Delivered on time this machine is fast assembly without any worries. The drive is appreciable. The many settings are perfect either your body or some field work. Autonomy is approximately 30mm in maximum power which is good! Recharging is a bit long but it does really matter because we recharge when not in use otherwise buy another battery. The trimmer is light enough and wire feed works without manual intervention. Even in high no worries herbs. It remains to see to wear, not of metal or of a mixed plastic alu .. pretty solid. The overthrow of the head is very effective. PS: I have no relationship with Black & Decker ... private individual handyman.
