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.

String Guard Very difficult to install.
Would Not RecommendThe string guard did not properly align to holes. I had to force it to line up, it still isn't prefect and I am incredibly dissatisfied about this. I worry that it will not stay attached properly over time. Come on guys, you can do better than this.

heavy & hard to balance
Would Not Recommendits much heavier than it looks. it's tiring after a short period of time. It's bulky, hard to find a comfortable way to hold it. It might get better once I use it more. The head guard screws are too short! I had to take it back to Lowe's and get assistance. A Employee had to get longer screws.

Get the extended warranty
It works great. But this is out second one. After a couple of years the handle broke off! But without the warranty or receipt there wasn’t anything to be done. This time we got the extended warranty.
