I've used it on some smaller limbs that fell in the yard after some storms. Most limbs were 6" or less in diameter and the saw handled them easy. Biggest test i gave it was a 10" or 12" diameter tree thar fell at the shop. Anything that big will burn through a 5amp Battery pretty quick and the saw really needs a forge battery. That being said, the smaller stuff, 6" or smaller is perfect for 5amp batteries and this saw.
Im getting rid of it because im going back to active duty army service and on-post housing. There wont be any trees in my area or barely a yard. I wont need it. Asking $200 or best reasonable* offer.
