Sorry I don't have one. They have always looked interesting, but not for almost 70 bucks. Have you ever used one? Are they metal or plastic?

I really want to buy a used one because it would save me a lot of money and I am having a lot of trouble edging with my echo srm-225 because of its weight. I never used one before. It's made out of ABS plastic and weighs only 7 oz. There's one for curved shaft trimmers too, Stihl, Redmax, and Echo I think, and it's only $25, but it's not as good as the one for the straight shaft.
