What Customers Are Saying
The product is a lightweight and powerful tool for trimming around the yard, with a long battery life and easy assembly. However, some customers reported issues with the string not feeding properly and the battery life being too short for their needs. The trimmer may not be suitable for heavy-duty tasks or those requiring extended runtime. Customers recommend checking the availability of replacement parts before purchasing.

Enjoyed it out of the box... then I had to replace the line. Went online for instructions. Instructions were easy, replacing didn't work the way the video said. Went back to Lowes with it for help. Staff member couldn't figure it out either. Even with online instructions. Will not buy this product again.

Frustrating
This trimmer worked great ..and I liked it....until it needed new string. It was the most frustrating task and if knew....I would have never purchased it! I do not recommend.
Hi there, Lyv2! Thanks for sharing your experience with our String Trimmer. We’re glad to hear it performed well for you initially, but we’re sorry t...

First use impression
So, I bought this at the end of the year last year and didn't use it until last week. The Battery was still charged. I was amazed at how light it was, how quiet it was and how well it worked to trim my weeds - compared to my old gas one that died. I have two Kobalt battery chain saws that I love so I expect this to be a good purchase, as well.
Tool went bad. Trigger switch. Totally dead.
Had it about 3 plus years never had any issue till today. Triggered switch I’m thinking made an odd noise odd feel when I pulled trigger. Anyways it’s dead. Went to Lowe’s service counter she said had to call Kobalt warranty service. Called them he could not find my purchase date on the my Lowe’s account which I know I always used. He said can’t do anything no receipt. I said that’s why I use my Lowe’s on every purchase. Store won’t do anything so what just forget the 5 year warranty. ...

Battery Powered String Trimmer
I have used a gas powered string trimmer for decades. It is both heavy and loud. I decided to try this string trimmer because it is light-weight and operates on a lithium-ion battery. I am surprised at how powerful and long lasting an electric trimmer can be, and quiet! I have a corner property with a lot of curbing to trim. The Kobalt string endures the contact with the curbing a lot longer that my previous cutting string did. The light weight of the trimmer makes the job so much easier. I need...

no replacement spools available
I purchased this trimmer last March with 2 extra spools that were supposed to fit my model. I just used up the line that was on the pre-installed spool. I opened one replacement spool and then took of the cover to replace it. To my surprise the replacement did not fit and did not look anything like the one that came with the machine. There is no spool available that fits my machine. I talked to the Kobalt customer service and they couldn't find a spool that fit my model. In fact the man I tal...

Open the box and check your product before walkin.
The weed wacker is great HOWEVER service at lowes was a joke. I ordered and paid for the item the day before pickup online. When I picked it up, i was given a “returned “ product. The box was torn, banged up, and taped shut. I told the customer service person I wanted to look at the item before I took it . The item was loose in the box, no packing and obviously was handled by someone. I went back to the lawn tool area and there was a display that had numerous of these weedwackers. I had a very n...

Poor Battery life is the MAIN ISSUE
When this Kobalt 24 vdc string trimmer is fully charged, it works pretty darn well, BUT for only about 10 to 15 minutes of use. Then it takes over 2 hours to fully charge the battery again. Sure, I can purchase a few more batteries but at $70 each, two would cost me more than the trimmer package which came with one battery. 2 hour charge time for 15 minutes of use is not a good ROI. Will be returning for an electric trimmer with a cord.

Needs a bigger/more battery
Got about 10 mins of run time before it drained the battery on the low setting. I wasn't even hogging though anything difficult either. Just typically trimming around trees and my house. That's just way to short of a run time. I would need 2 batteries minimum in order to do 85% of my yard. I even tried to charge it for an hour while I mowed and then run the trimmer again and it only ran for about 3-4 mins before being out of juice again. I like the trimmer itself, it was light weight and plenty ...

No comparison
I got this Kobalt trimmer as a replacement for the Ryobi that I had had for 10 years. Kobalt is a name brand that holds a prestige so my husband really thought that we were trading up. However, after three attempts to love this trimmer, I found that my Ryobi was superior for the following reasons: 1. The Kobalt lacks the power to trim any growth that is up against a rock or metal box. I find myself moving the trimmer end around, trying to find a position which would allow the trimmer string to c...
