The first thing you notice about the Black & Decker BESTA530CM-QS is the wheelbase. When you place the string trimmer on this base, you can use it as a lawn mower. If you're working without the base, then you're holding a 550-watt string trimmer. With the string, you can trim your lawn edges back to perfection in a 30-centimeter trimmer swath. On top of that, you can set the telescopic tube to a length that's comfortable for you. The pivotable head ensures you can also trim in hard-to-reach places, and cut the lawn edges neatly. You can do this with ease, thanks to the edge guide wheel. After use, you can store the BESTA530CM-QS compactly in your shed.
