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 RecommendProduct is trouble free and convenient. A bit pricey versus loading the reels on your own. But saves time especially if you run out in the middle of trimming.

Trimmer spool
Would RecommendWorks as you would expect tends to stick to itself making it harder to extend the string.

NOT for use with the Kobalt Dual string 40 v model
Would RecommendThis is probably a good product, but the label is VERY misleading. It states for use with 40 volt Kobalt trimmer. Maybe an old version but NOT the current 40 volt DUAL string trimmer; be careful. Unfortunately I had to return these, and worse, the correct spool / line was not in stock.

Best string for yard trimmer
Would RecommendWe have a Kobalt yard trimmer, and this line was the best. Unfortunately, the spool doesn't fit our model so we have to unwind all the string and rewind it on the correct size spool, which Lowe's doesn't stock.

Problem experienced using this spool
Would RecommendOn three different spools I was unable to use all of the line. I don't know why this happened that a lot of the line is still on the spools.

Kobalt 3 pack 20 ft spool of 0.065 trimmer line
Would RecommendThe Kobalt battery line trimmer is excellent for lawns, brush, even edging. But it does not bump-feed well and needs to be turned over and manually triggered to feed more line. However, it does feed too easily when the line gets grabbed by a thick stem. So it uses up a lot of line in the course of a day or two. The 3 pack is good to have extra spools on hand. They pop in easily and are good to go. They seem quite expensive compared to wind-it-yourself line, but that process is a real pain.

Gets the job done
Would RecommendOrdered this. It was silver string not blue. I just wish it was stronger and broke less.

Kobalt spool
Would RecommendEasy to install. But runs out quick. And expensive.

Wrong product
Would RecommendReturned .... but they at least triple over priced . Shouldn’t be more than $6.00. Always shameful how grossly over priced after market prices are ... and for the record - I despise the trimmer I was trying to buy a spool for because the bump head is junk! My worst ever Lowe’s mistake!

Only drawback is the difficulty putting the string in without it all unraveling. But soon you get the idea.

No chance. I liked the replace string.
Would Not RecommendI like the replaceable string set that came with the unit. The company stopped making it. I had to turn in the weed wacker.

Expensive and not durable line
Would Not RecommendThese are very expensive for the short amount of line on each spool. The line is not very strong and breaks easily. They are hard to restring by yourself, so pretty hard to save money. If it was a 5 or 6 spool package at the same cost, I would like it better.
