Quite powerful and effective. The "kickback" is avoided if you let the weight of the machine do the work without pushing the wood yourself. The unacceptable thing is the tensioning of the chain. It has a fake bolt on which the whole blade attaches and easily comes loose. I don't see it lasting long.

The kick is excessive. Be careful with your hand. The first battery lasts for 5 average tree pruning. If you have 5 batteries and handle them with great care, you will make it through the day. Otherwise, it is very good.
