Someone said one star is too high a rating for this product. I completely agree. I have two Stihl brush trimmers, an older FS106 and a much newer one. This will not fit properly on either, despite the manufacturer's claims. Even took it to a shop to see if they could get a good fit that didn't vibrate dangerously. No luck. It's trash. Looks like a nice idea, but beyond worthless. AND, I even bought the “deluxe” model hoping for a nice product.
Bottom Line: No, I would not recommend this to a friend
