I’ve owned one for two years now , and it’s been a fine big saw , ergonomically it’s really nice, doesn’t seem like a 90+ cc saw , and good amount of power for the big stuff, the Auto tune 3.0 works good , I run .404 on 32” bar and pulls it well , there were some issues earlier in production , but new stuff has that , did do a muffler mod and a couple other things, but nothing really to complain about , if you have big stuff to cut , it will fit ur needs,
