The chain saw is excellent. Good feel and runs smoothly. The only issues are battery length and size of logs to be cut. The battery does not last well when logs are more than 12".
Cuts through hardwood just like a 42cc gas saw if not better. Good design and seems well constructed. Don't expect a very long runtime if the bar is fully buried in hardwood. Maybe 15 minutes on a 4ah. But even a gas saw would need refilled shortly after that.
I bought this to prune & trim my trees it works very well , has a long lasting battery performance , I am thinking of getting there inverter & another battery for emergency & recreation.
This is so easy to use - start/stop/pause, etc. Seems as powerful as my gas chainsaw although I did not get to see how long the battery will hold up as I only cut a couple trees.
