I have always had positive experiences with Stihl Equipment, So I figured I would pick up a Bagger/Shredder Vac because my wonderful Echo is already wasting after the first year. 10 minutes into using my shiny new toy, I felt like i was shot in the leg. My leg was bleeding and I was standing there like "What the &%&??" Turns out that the vac picked up a stone and shot it through the plastic housing like a bullet. You must see this thing....Umm, do the engineers test this stuff in the field??? Anyone have this happen to you?
