What Customers Are Saying

The Kobalt cordless string trimmer offers a powerful 80V brushless motor that can handle thick weeds and tall grass effectively, comparable to gas-powered models. It features a long-lasting 2.5Ah battery with quick recharging, providing over an hour of runtime. The lightweight and well-balanced design is easy to maneuver, though some users find it a bit heavy. The trimmer operates quietly and offers adjustable handle and two speed settings for good control and flexibility. However, some users struggled with restringing the trimmer head, and there are concerns about the availability of replacement parts and long-term durability.
