What Customers Are Saying
The trimmer line is a mixed product, with some customers finding it convenient and durable, while others report issues with jamming, quick wear, and difficulty rewinding. The pre-wound spools are seen as a positive feature by some, but the replacement spools are considered overpriced by others. Overall, the quality and performance of the trimmer line seem inconsistent, with customers advising to try it out but be prepared to potentially rewind the line themselves if the pre-wound spools prove problematic.

Would RecommendDecent pack of trimmer line for normal household projects; a bit light for the heavier weeds I was dealing with.
Great Product
Would RecommendI've been using my Kobalt trimmer for about 4 years and go through about one spool a year. I trim about once every week or two. I've been very happy with Kobalt trimmer and the line spools and haven't experienced issues.
Service
Would Not RecommendYou sent it to the wrong store for pickup and provided no assistance to fix the problem.
Very cool but doesn’t work.
Would RecommendFirst I want to communicate that the idea is awesome and I was super excited and satisfied with the kobalt products. BUT today I learned that the “fast changing spools” are not compatible with my 24v weed eater.(was not informed about this little detail) Now I have to return them and spool up the normal way vs this fast and easy way.
Works well
Would RecommendI purchased a Kobalt 40 volt line trimmer about 8 years ago. I also purchased the 3 pack of .365 spare spools giving me a total of 4 spools. I purchased the universal 275 foot of .065 blue line. I have been rewinding the spools for 8 years and just rewound 3 spares using the last of the universal line. This should last me the rest of summer 2021 and more. Trimmer is very handy, no cords, gas or mixing. I have the 40 volt blower too and a total of 3 battery packs that last 45 minutes each.
Breaks too easy
Would Not RecommendBecause the product is weak it breaks easy. I use a whole roll every time I trim my lawn

Kobalt refill spool
Would Not RecommendThe item pictured was what I wanted, was told at the store those aren’t available anymore so they pointed me to the refill for my weed eater. I bought the item and put it in my trimmer, didn’t feed right when ask to, spool was a little different size, plus the string was different. I guess I have to buy a new weed eater now to get efficiency. Just what they wanted I would say
