Honestly I expected some of the issues I had with 372s and the very reliable G660 , but nothing of note.
I have some spare parts on hand figuring something would be off ,carburetor, tensioner, or on/off switch.
Carburetor malfunction was always an issue before whether it was incorrectly assembled or had garbage in it, stripped screws from my G372.
Of course time will tell and I have too many saws for it to be pushed too hard. I have worked my other knock offs on particularly hard days and jobs and even use it in chainsaw class for the students to use. Basically if monetary gain was my goal I would have more than quadrupled my cost of them .
