I've had this machine for three months and I can only speak good things of it.
My dad who is 56 and works for me was always complaining about the Stihl FS85 on how heavy it was and the vibration through the shaft.
This thing goes like the clappers, far more fuel efficient than the 85 and rips through grass like you wouldn't believe.
They've also installed a throttle trigger which cannot be broken as it's made of a malleable plastic.
Wouldn't think twice about buying another when I need one.
Hoping long term this machine proves itself.
