It is good only for trimming grass where the mower cannot reach (around tree trunks and edges). If you catch a thicker piece of grass, like a cigarette, it struggles. However, I bought it only for the grass so it does the job well. Overall, I would like it to be more powerful. The build quality is good. The main reason I bought this brand is because I also have a drill, so I use the same charger and battery which are very good.
