AustraliaPowerhouse that never quits.
Puchased this saw on special and did not regret it once I took it out to cut 20inch round iron bark trees. Although this saw was about 1kg heavier than my ms391, it cut iron bark far quicker and allowed me to spend half the time cutting as I normally would. It never skipped a beat and didn't even require a sharpen through two downed trees. Anyone that buys this saw will be hugely impressed.
