Light weight, sharp cutting chain. Reasonable battery life to cut an evenings worth of wood for open fire.

It is lightweight and has good safety features. The instructions were clear and concise. It is a very handy tool for garden maintenance of trees and thick shrubs.
I had a bit of a game fixing the chain initially, I am left handed so put it down to that!
