We have one of the really small sthil ones, i ridiculed my father for buying it, everytime he sees me get it out to use he has a very satisfied look on his face! Great machine but battery too small. We bought some extra batteries. It's now done a lot of work and worn a few chains out. Really easy to pull apart when jammed, no tools required. I think the genius of them is the chains are so thin so slice through really fast.
We have no an xp395 husqvarna, if you can start the bloody thing it will cut through anything, thats my go to saw when i need power. My go to for general farm work is the stihl mini boss.
