Same summary

The DeWalt DCMST901N-XJ 54V cordless string trimmer is ideal for users looking for an efficient solution for trimming lawn edges and hard-to-reach areas in medium-sized gardens. The cutting width of up to 42cm also allows for faster work in open areas, but it should be noted that the trimmer does not include a battery or charger - so it is best suited to those who already use DeWalt's 54V battery system. Due to the higher voltage and larger cutting diameter, it will be slightly less suitable for very narrow or complexly shaped gardens where maximum precision around the edges is required.
