What Customers Are Saying
The trimmer line is generally effective at trimming, but some customers experienced compatibility issues with their specific trimmer model, leading to difficulties with installation and frequent line breakage or jamming. While the line is considered a convenient solution by many, some feel it is overpriced compared to manually rewinding the line. Customers suggest the manufacturer could improve the product by offering more size and color options, as well as better instructions and customer support.

Would RecommendBest line I've ever used, none of that thin fishing string line that I've used with other trimmers that gets eaten up pretty quickly. This line is great for both trimming and edging.

Do not buy items like this online, go to the store
Would Not RecommendWhile the product itself may be good, it is not the one that fit my trimmer even though it says it would so I hade to unroll the line from the new spool and re-wind it on my old trimmer spool. Basically I paid a higher price for a pre would spool for nothing as just buying the trimmer line itself would have given me much more line for the same amount of money.

Multiple Problems
Would Not RecommendI have had problems with this product. It is very difficult to install, and once installed the bump feed does not feed. I have to manually remove and pull line through. In addition, I figured maybe I got a bad part, so I attempted to purchase another one, and cannot find it anywhere, Also, the model number for my trimmer (KST130X-06) is not coming up in a search. Was there a problem and it's been replaced?
