What Customers Are Saying

The Kobalt 40V trimmer spool has mixed reviews. Some customers found the spool easy to install and the trimmer line to be of good quality. However, many reported compatibility issues, with the spool not fitting their specific Kobalt 40V trimmer model as advertised. Some also noted the trimmer line broke easily or did not last as long as expected. The spool may work well for some models, but customers should carefully check compatibility before purchasing.

Be careful - not all 40v Kobalt are the same!

Would Not Recommend

It was 100% wrong - the words for "older 40v" weed whip are not on the package. I bought this for my newer unit, and it does not fit. Very annoying.

Does NOT fit older K40v

Would Not Recommend

I bought the Kobalt string trimmer KST104B03 just a few years ago as a backup for my Pro Craftsman while being serviced. The KOBOLT is a terrible trimmer. The replacement spool can NOT fit in the older models with the white spool. Following the internet videos to restring the original spool never got factory tight. Do not buy this trimmer line replacement spool if your original spool is white. It’s not the right replacement line.
