That it will work on a Stil weedeater
Style: 9" 2T Cutting Blade
The edger connected to my Stil weed eater and worked great. I would recommend it to anyone.

Cut edges like a pro
Style: 9" 2T Cutting Blade
Better, much better than the OEM yellow and black brand. This has an all metal guard and the blade does not bind when it comes into contact with concrete. I have used it all summer for edging two commercial properties and my own lawn, it’s still turning and cutting with ease. Being all metal adds weight but the trade off over fragile plastic is worth the durability.

OK for light duty use only
Style: 9" 2T Cutting Blade
Not very strong or robust. Does fit my power head properly. Only recommend it for occasional, light duty use.

These work for the Worx trimmer WG928
Size: 16 Line Spools+4 Caps, Size: 16 Line Spools+4 Caps
Recently purchased the Work String trimmer and blower bundle. I found these and ordered them in hopes they were the right ones. They fit and work perfectly. Super easy to install. Pop out the old one and pop in the new. The string is pretty durable and thick. I love the idea of pre loaded spools. It got so annoying having to rewind the string on the spool every time I ran out. Price is fair and worth it. Highly recommend these if you have the same trimmer.

Worth taking the worry off my list.
Size: 16 Line Spools+4 Caps
Great to last forever and not pay over priced smaller packages.
