Ratings may include incentivized customer reviews.
What Customers Are Saying
The battery-powered trimmer provides good performance for most residential yard work, with a long-lasting battery, two speed settings, and a relatively lightweight and easy-to-use design. It cuts through grass and weeds effectively, though may struggle with thicker vegetation. The main drawbacks are the difficulty in restringing the trimmer head and the lack of availability for replacement parts. Overall, it is a solid choice for homeowners with small to medium-sized yards who want the convenience of a cordless trimmer.

Would RecommendUsed 2 seasons and still working. Used for about 1.5 hrs a week. Works well in grass and smaller weeds.

Died after 3 years
Would Not RecommendJust took it out to use after winter and it no longer works. I tried three different fully charged batteries and nothing. Called Lowes customer service and found out that since I didn't keep the receipt the warranty is useless. Will look to buy a different brand.

Good product but skimps on extra spools.
Would Not RecommendIt is a solid tool, works well and more than enough battery to do a whole yard plus some. It is a bummer that this company cannot include an extra refill spool pack. Most other companies, even lower models of Black and Decker or Greenworks came with a refill pack. For the cost, they should include at least one. Would look at other brands before buying Kobalt as a refill spool will set you back $20 anyway.

Electric powerful string trimmer
Would RecommendIdeal for a homeowner with a small to medium size yard. However, I must add that I've done some very big jobs with it. Light weight, easy to use, and it's electric. Run around 45 minutes on a charge.
