Perfect Fit and Hassle-Free Replacement!
What I Like: Perfect Compatibility: These spools fit my BLACK+DECKER trimmer (specifically the LST300 series) perfectly. Just pop them in and you’re good to go — no manual winding or fiddling required. Automatic Feed Works Great: The string feeds out exactly as it should, which saves me a lot of time and frustration during trimming sessions. It keeps the job moving without having to stop and adjust. Good Length & Quality: Each spool has 30 feet of 0.065-inch line, which is more than enough for several uses around a medium-sized yard. The line is durable enough to handle light to moderate weeds and edging. Convenient 3-Pack: I love that this comes as a set of three—it’s cost-effective and means I don’t have to restock constantly. 📝 Final Thoughts: If you own a compatible BLACK+DECKER trimmer, this 3-pack is a no-brainer. It’s reliable, easy to use, and makes yard work that much simpler. I’ll definitely be buying this again when I run out!

Very cheap and easy fix
Great product. The auto feed on my Black & Decker weed trimmer had not worked correctly for about two years. I thought I was going to have to buy a new trimmer. I never thought that the spool was a replaceable item. Took seconds to replace the spool and viola, the trimmer now works like it should. A very cheap and easy fix. Hopefully I can get several more years out of my trimmer.

OEM for Black and Decker and works with Craftsman!
OEM replacement works best! Tried another brand and had issues with it. Craftsman ( also made by Black and Decker) can use these.

Costly
Fit and use perfectly for my weed whacker. A bit costly but good product.

Easy as Pie
Love that I can just pop them in to the weed eater. No more winding which was always a pain and would jam most of the time. Worth every penny.

Easy replacement string
I use these on a lightweight black and decker weed-eater that I keep at my daughter’s townhouse. These fit perfectly and last several seasons. Not much else to tell.
