Review on Eventronic Replacement Spool For String Trimmers - 4-Pack Of AF-100 Autofeed Weed Eating Spools - 0.065" Diameter - Not Compatible With Smart Power Weed Eater by Shannon Judd

These worked well. But not much on the spool. Or I just blew right through them. I got one day of trimming and edging done on one spool. I think it should be more. My yard is not huge by any means. I saved the spools and bought more string, to restring them. Cheaper than buying more of these.
