Note: you have an 070 pic and a 660 jpg file name attached so I'm not sure what you are interested in.
The guys on youtube seem to like theirs. Try KimballCody's yt videos to get an idea what they are like. This is his unboxing and he has several others of it running and milling. Slow, heavy and torque are the main descriptions I hear a lot vs modern 90cc class saws. No reason to get one other than long bar milling for me since my 660 does great with a 36" mill / 42" bar.
