Hi guys. I live in West Australia and we cut a lot of local Jarrah hardwood with these saws. I have built from the kits the 070, 660 and the 440 I also purchased a ready built G660 blue thunder. These saws go hard and are awesome quality for the price, the 660 eats hardwood. I also own a genuine Stihl and can honestly say the farmatec saws perform just as well for a fraction of the price. Can send pictures if interested
