FUTURE WAY STRING TRIMMER REPLACEMENT SPOOL LINE: 0.065 18-Volt 24V 40V, Compatible with Ryobi One+ AC14RL3A, Weed Eater String Cordless Trimmer Line 11ft, 8 Spools
It Works, and It’s Cheap.
It’s the same exact stuff that you can get at home depot for about $25 for a 3-pack, for about 1/5th of the price. Enough said.
I wish I had thought to check amazon the last time I needed trimmer line, but at least I know never to get this stuff at HD in the future.
