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.

Almost perfect
Would RecommendThe line is tough enough and relatively easy to replace but the way it is wound on the spool it "locks up" on the spool and stops auto feeding. It should be wound on the spool in such a way that the line will not cross over other line in the spool and stop feeding.

Over a barrell
Would RecommendI mean, it’s the only spook that fits but it’s a 3 pack that costs $20. It’s highway robbery. It’s not like the pack will last you all year if you have a moderate workload either. It is what it is.

KOBALT --IS THE ANSWER
Would RecommendAFTER USING OTHER BATTERY YARD APPLIANCES THAT DID NOT WORK I HAVE SINCE GIVEN THE KOBALT LINE A TRY AND THE EDGER, TRIMMER, AND BLOWER ARE AWESOME. THESE REPLACEMENT LINES GO IN EASY AND WORK WITH NO FUSS. GREAT PRODUCT. LITTLE PRICEY AT 3 FOR $ 20 BUT WORTH IT.

Thought this spool would fit my 80 volt but it did not and had to wind by hand-not a problem, just took some time.

Easy to use with Kobalt Trimmer/Edger
Would RecommendWe have the rechargeable Kobalt Trimmer/Edger and enjoy using it. We have had it for several years now. The ease of loading the trimmer line is very good. The only reason I did not give it 5 stars is that they are expensive and are used up quickly on large yards. Also, since we go through so many line holders it would be nice if there was recycling available on the empty line holders.

Lonely trimmer lone
Would Not RecommendComes in three spools! Spools get used very quickly on a very small yard and they aren’t cheap! Would rather have options on which line/accessories to purchase but that isn’t possible with this unit.
