I almost can't believe it. I bought 2 five pound spools of .105 string trimmer line and its durability is so poor, it's astonishing. I almost can't believe how fast this stuff is falling apart on me This stuff is garbage! I took one of the spools back to my dealer/repair guy telling him this is the worst string trimmer line I've dealt with in years and years. Man, I've got to reload the string trimmer's spool with like every lawn! It doesn't last! I'll never buy RedMax string trimmer line again. It's terrible. Before I always bought Lesco's line or Kawasaki's. Who makes a really durable string trimmer line besides them? Any suggestions?
