I could do a groin 40 meters from a pretty high hurdle without recharging, it is very effective on branches size less than cm. It has a bit more difficult when it becomes thicker. It is perfect on biennial cuts. The device is a little heavy and the weight (motor) on the front which makes handling at the end of a little tiring arm. The battery 2A is enough for 2 or 3 hours of work. The telescopic part is quite small, it lengthens as a 30 groin centimeters.
