That's funny, cause I saw a catastrophic flurry of epic proportions over about a five year period where sawhands were left out in the cold by husky after their brand new saws burnt up or had bottom end failures after only a few days on the job. Nearly none of them could last a season, or maybe 1/3 perhaps up to 1/2 to be fair. They became throwaway saws. One season (if they lasted) and down the road they went. Bad gas, apparently. Right.
since you have no direct experience, or claim not to, perhaps you should educate yourself.
5 series saws were a mess to start with, and it continued for years, then the autoboom started...
I don't know how you cannot know this. Perhaps you talk the talk but haven't done the walk, idk.
